Xanthichthys auromarginatus,
repro. 4/25/08
Hello and good morning. I have been searching for info regarding breeding
habits of Xanthichthys auromarginatus. All I have found so far is nothing. Could
you point me in the direction of anything that discusses their breeding habits,
be it in the wild or captivity.
Thank you very much,
Mike Nance a.k.a. Reefmike - DFWMAS
<Hi Mike... don't know that there is much to state re the genus reproductive
behavior (some spawn in deep water...), most are bentho-pelagic... live in the
upper/mid water column in deep/er water... Have seen this species making
spawning nests, though... in Hawai'i... So I suspect it is a/the usual balistid
pattern of male nest building, attracting females, poly-mating, guarding the
eggs... till hatch out... Bob Fenner>
Re: Xanthichthys auromarginatus, repro. 4/26/08
Thank you very much for the reply. It is greatly appreciated!
Could you describe the nest building that you saw (materials, location, etc.)?
<... sandy bottom, about 40-60 feet in general... individual males digging a
smoothed out pan/area of a couple feet diameter, swimming up/down apparently
trying to attract females>
If you decided to attempt breeding a pair what would you do as far as set-up
(tank size, substrate, rock, etc.)?
<The larger the better... hundreds of gallons... some mixed rock, sand areas...
not too many other species of fishes mixed in...>
Sincerest thanks,
Mike Nance a.k.a. Reefmike - DFWMAS

Re: Xanthichthys auromarginatus,
visiting HI 4/28/08
Again thank you very much for the replies. I know y'all are very
busy and I am very appreciative that you take the time to answer sooooo
many questions. I can't even imagine the amount of email you must get on
a daily basis.
<A handful... though all could be...>
Anyway, back to the subject.
I have been told (and read) that they can be kept in a harem (1 male, 2
or 3 females). What are your thoughts on this?
<Can... need a very large setting... several hundred gallons... Likely
very worthwhile for you to get/come out and observe this species in the
wild... lives in a sort of Lek territory... of a few hundred to thousand
cubic feet... not really in "pairs" or permanent associations of any
sort... do "run off" same and alternate sex individuals...>
I'm planning on starting with juveniles. 1 male and 3 females. I'm going
to grow them out in a 100g then move them to at least a 240g as they
reach adult size.
<Will need more room than this>
I'm thinking just them with no other fish in the tank though I wonder if
they might not be more "comfortable" with a school of "dither" fish such
as chromis. Your thoughts?
Thank you and have a spectacular day!

Big Island/Kona... Observe the other life, habitat... will grant you
real input. Bob Fenner>

Sargassum Trigger...Adapting
to Captive Life 3-30-08
Hi Crew,
<<Key Kirk.>>
I have a Sargassum Trigger set to arrive on Wednesday from an online company.
<<Exciting.>>
While I have kept several different Triggers successfully (Niger, Huma,
Rectangle, even the dreaded Undy) in the past, I am a little nervous about my
new addition. He will be the most expensive fish I have ever purchased, and the
only Trigger I have kept that is considered somewhat challenging to keep in
captivity. I often frequent the various message boards to learn, yet rarely see
any info on this fish being kept.
<<Yes, they are definitely a more elusive species to collect than the ones you
mentioned above. Also you have to take into consideration that Xanthichthys are
pelagic triggers relying heavily on zooplankton; thus they do not adapt as
easily to captive life. I would quarantine for a minimum of a month and avoid a
large variety of foods, feeding relatively small amounts multiple times daily.
Try mysis, mysids, krill, clams, scallop meant and finely chopped meats of a
marine origin.>>
Tank is a fairly new 240 8x2x2, 160 lbs LR, 160lbs LS, custom sump with
refugium, Aqua C EV 240, and Emperor Aquatics 40 watt UV, his new friends will
be a juvi Sunset Wrasse, baby Niger, and Flame Angel.
<<Watch for aggression between this animal and the existing niger.>>
Just hoping for a little advice as to why this fish sometimes doesn't flourish
in captivity.
<<See here;
http://www.wetwebmedia.com/marine/fishes/triggers/xanthichthys/index.htm along
with the linked FAQ’s and my above listed notes.>>
Thanks and best regards,
<<Good luck to you and your trigger.>>

Trigger Update...
lost Sargassum -11/27/2007
Good evening Bob & Crew,
<Mike>
Snowing here now, so feel good if you're diving in Hawaii,
<Was ayer... very nice... about 82F., clear... Neener, neener, neeeener>
or anyplace warm.
Alas, the Sargassum did not make it. Man, that's a few this year! Up
until now I could have said that either another fish killed them, or I
did, but I "think" this one was different. I could say I lost him, but
in hind sight, I'm not sure I ever really had him. He was already
slightly pinched in at the LFS, so I watched him for over a week. He was
still active, alert, eating and seemed stable enough (although still
pinched). I thought I would just have to fatten him up at home. No such
luck and another lesson learned - "Buy ones that are already fat"!!
(hmmm... where have I read that before?)
R.I.P. Sergeant Gas-em, and my nine year old son is no longer impressed
with my skills.
<A hard, but necessary lesson>
After many hours (and hours... and hours - before, during and after) of
reading WWM articles and FAQ's, at least this time I can't come up with
a list of "would have, could have and should have" things that I missed
(other than buying a fish that was thin, of course - everyone wants to
be Mother Theresa in this hobby it seems- even guys).
<Mmm, yes. And we are neither infallible, nor immortal either>
The only thing I could come up with at all was if I had, perhaps,
treated for the "possibility" of an internal parasite while in QT. I've
often read that you should not medicate when you are not certain what
you are trying to treat.
<Both approaches have adherents. There are VERY large facilities that
treat prophylactically...>
There was no sign of weight loss while in QT and when he started to go
south on me in the display tank, he went down in a hurry. By the time I
really knew there was something wrong, I would have needed some dynamite
and a crowbar to get him out of a hole in a rock at the bottom of the
tank. I did manage to get him out the next day when he was lying on the
substrate (when I e-mailed you - thank you for your response) but he was
gone by the next morning. Is there such a thing as treating for internal
parasites during QT "just in case"?
<Yes>
Is this ever a preventive measure?
<Yes>
Other than a freshwater dip, is there anything else that could be /
should be considered as routine during the QT stage?
<Some folks use anti-protozoals prophylactically... some add
Vermifuges... there are other protocols... but I'd rather not post them
in this public address... for "fear" of encouraging others too
much/inadvertently in pursuing such...>
Another reason I'm asking is I have a beautiful 2" Flame Angel
(brilliant colour and not at all thin or with any signs of problems) in
one QT tank with LR and sand - and another really beautiful specimen of
a Copperband Butterfly (not quite 4" - spotless and as smooth as silk -
alert and active) in another tank with LR and sand (after I read hours
of material on the challenges of keeping this particular Butterfly prior
to purchasing - I actually added a rock with Aiptasia on it to his QT
tank as an experiment - now how crazy does that one sound?
<Not at all... are food for this species... used often enough as
"chemical filters"...>
- another experiment of mine like QTing some fish with a cleaner shrimp
to help distress them - hey, that one seemed to work - we'll see about
this one). Just wanted to know if there is anything else I should /
could be doing for these fish while in QT? I'd try soft music if I
thought it would help.
<Might... at least calm you>
One last point, if I may. The Flame was a bit of a no-brainer choice in
fish (mind you, only a no-brainer because I have your book and burn the
midnight oil on WWM), but the amount of information available on your
site regarding selection, compatibility, behaviour, disease, the feeding
challenges etc., etc., "specific" to a Copperband Butterfly was
phenomenal (forgive me but I have to admit to liking Anthony's trick of
feeding the clam and then stuffing the empty shell after with prepared
food the best - that is a great trick).
<Is an oldie, but goodie... Pre-dates Antoine, myself even!>
I have yet to find another resource (and I do look) that comes even
close to what WWM has to offer. You just can't buy that volume of
information on a single type of fish (well... you could read WWM and
then donate through Amazon I suppose - ok, ok I'll make another donation
- I'm probably due again anyway).
<Heeee! Thanks>
Just in case you need any more reminders that you are all doing wonders
for this hobby, I originally just wanted a small freshwater tank with a
few floaters and a couple of bubbles - then I read Bob's book and found
WWM - and now I'm up to four established tanks (including QT) with
Tangs, Angels, Puffers, Clowns, Hawks, Butterflies, Corals, and a host
of other living things that I have to check my notes just to remember
their names, not to mention enough equipment to land one of my tanks on
the moon. I have referred quite a few people to your site and they are
equally impressed - and strangely enough, some of their tanks are
getting bigger too?!
<Madness, madness, I call it madness...>
It's not always easy (or successful), but it's always worth it - and you
all help a great deal.
Thanks again, eh.
<Thanks again... you hoser!>
Mike from Canada
<BobF, in Kona>
Need some advice on my fish list
for my 150-gallon
Pull The Trigger? (Considering a Triggerfish in Stocking Plan)
11/26/07
Hi there everyone,
<Hey there! Scott F. in today!>
I'm hoping you guys can help me out. I've been reading through the
website and I must say I've learned an awful lot.
<Glad to hear that! We have some cool people who work very hard to bring
it to you every day!>
I'm going to set up my first saltwater tank and I need some help with my
fish list. The tank is 150 gallons and measures 48" long by 24" wide by
30" high. It's going to be a future reef tank lightly stocked with LPS
and fish. After doing some reading on Tangs I've decided to stay away
from them, as I've learned they really need a six-foot tank to thrive.
<I think that you made a responsible decision!>
Anyway, here are the fish I'm hoping to have: 1 Bluejaw Trigger
(Xanthichthys auromarginatus), 2 common Clowns (Amphiprion ocellaris), 1
Orchid Dottyback (Pseudochromis fridmani), 1 Sixline Wrasse
(Pseudocheilinus hexataenia), and 1 Coral Beauty Angel (Centropyge
bispinosus). What do you think of these fish for this tank? I'd greatly
appreciate any feedback and any other fish suggestions you may have.
Thanks in advance,
Shannon O'Rourke
<Well, Shannon- I think that you put considerable effort into
researching and developing this stocking list! My only reservation
(always seems to be one, right?) is the Trigger. Although this species
is certainly one of the more "passive" Triggerfish (an oxymoron, huh?),
it can display some aggressive tendencies on occasion, and it does have
much of the same dental equipment as the more nasty ones! There is
potential for this fish to nip or become more aggressive with age. My
friend had one that started out as a perfect gentleman, but grew into a
holy terror, taking out a few tankmates along the way. On the other
hand, I've seen others that were excellent citizens, living for years in
community aquariums without incident. It's kind of a dice roll, really.
If you are planning on keeping shrimp, I'd say that your odds of ending
up with an all-you-can eat shrimp buffet will increase as the Trigger
grows! Don't keep 'em with shrimp! Bottom line is that you could include
the Trigger in your plan if you're willing to accept the potential risks
that the fish poses. Do also keep in mind that this Trigger can hit 8
plus inches in size, and the need for larger quarters as the fish grows
must be taken into consideration. Hope this helps! Regards, Scott F.>
Crosshatch Trigger fading? 9/26/07
What's up guys and gals? Just wanted to drop a line regarding the crosshatch
trigger. I'm interested in this fish for an upcoming 10 foot long reef tank I am
planning. However, I had planned on keeping a pair, but I feel that they would
be lacking space, so to my question, does a male crosshatch trigger's color fade
if he is not in the presence of a female?
<Not much, but some, yes>
From every personal documentation of crosshatch triggers in home aquariums I've
read that pairs never exhibit any courting or interactions other than just
merely putting up with each other's presence. If this is the case, I might just
get a male.
Thanks for any help you can offer,
Nick
<Or even a small school if there's room... Xanthichthys spp. live in shoals in
the wild. Bob Fenner>
Re: Crosshatch
Trigger fading? 9/27/07
Thank you for the reply Mr. Fenner! Just a quick follow up, if I
were to do multiple crosshatches, would it need to be set up as a harem
or would multiple males get along together? Not sure if I'd go this
route, but I'm curious.
Thanks again!
<A mix of sexes would be fine to excellent here... Just try to
find/start them small-ish... four-five inches if possible. Have seen X.
mento in very large aggregations in the wild... BobF>
Male Blue Jaw
Triggerfish…Wants Female? – 09/08/07
Good morning and thank you as always for your wonderful site.
<<Hi Jeanne…we’re all glad you like it>>
I hope this one is an easy question.
<<Hmm…is there such a thing in this hobby? Easy, maybe…simple, never…
But I digress…[grin]>>
I have a small (5") male Xanthichthys auromarginatus (I have had him
about 3 months) in my 150 gallon reef tank.
<<Wonderful fish… I kept a male/female pair in a 375g display for a
number of years>>
Lots of zoos, leathers, mushrooms, a couple of Crocea clams -only one
coral banded shrimp and one large Sally Lightfoot crab and large Purple
lobster, because the stupid --and not at all shy, may I add--Blue Hamlet
ate all the other shrimp.
<<Mmm, not the fault of the fish…is what a Blue Hamlet does (will
happily gobble down small fishes too!)…as research “before purchase”
would bear out>>
He is such a sweetheart that I would like to get a female Blue Jaw
Trigger.
<<Triggerfishes are quite intelligent and seem to develop distinct
personalities…very easy to see how a fish-keeper becomes attached. He
may seem “sweet” (do be cautious if hand-feeding), but adding another of
the same species, even though female, may not be possible>>
Can she be added at this point without him acting excessively aggressive
to her?
<<Probably not…at least not by just “dropping her in” the system. The
pair I had were special ordered as such…likely collected as a
pair…subsequently quarantined/held together right up to their
introduction to the display…and even so, there was the occasional
nip-and-chase. If you are willing to go to the trouble… I suggest you
set up a holding/quarantine tank of “at least” 29g (bigger the better)
with some bits of PVC pipe or fittings large enough for the female to
hide in. Place the female in this tank first then add the male and watch
closely for a while, and be ready to intervene if necessary. Unless the
aggression escalates to the point where one or the other is being
damaged, keep the fish here and watch them closely for a few days
allowing them to become “familiar’ with one another. Maybe you’ll get
lucky and the fish will “pair-up”…but do also be prepared to
rescue/return the female>>
He ignores even the smallest fish--Pajama cardinals and the Royal Gramma
and Blackcap Basslet, but one of his own kind may provoke a different
response.
<<Indeed, this fish is quite compatible with most inverts/other
peaceable fishes in my experience…quite “reef friendly” in my opinion.
But conspecifics can be a whole different matter…especially so once a
fish becomes “established” as yours surely has by now>>
Thank you very much in advance,
Jeanne
<<A pleasure to assist. EricR>>

Sargassum trigger
comp.; Dog face puffer size – 07/30/07
Hi, sorry for another email, but here goes. I'm looking for some
info on a Sargassum Trigger.
<Xanthichthys ringens.>
A LFS has one and it is a gorgeous fish. I first read the bit on WetWeb
about its identity, and then the Compatibility FAQ on triggers. There
was one mention of the Sargassum in the compatibility FAQ, most are in
regards to undulates, clowns, and Picasso's, which, to my
understanding are quite different in temperament.
<True. The Sargassum trigger is more similar to the Bluethroat or Gilded
Trigger Xanthichthys auromarginatus. Both will reach around 1 foot, but
most often stay a little smaller.>
In my 200 gallon (72" x 24" x 27") I have a banded cat shark, a passer
angel (5"), a yellow tang and a dogface puffer (4"). I've had this
puffer for about 4 years, and he is really docile. He has been a 4" fish
his entire life, and I wonder if that is his adult length. Hmmm.
<Sure it is a dogface puffer aka Arothron nigropunctatus? This one
reaches 10 inches in the aquariums and more than a foot in the wild. I
have seen other Arothron spp. labeled as dogface, too. However, most are
even bigger. Hopefully his diet is varied.>
My question is whether or not a Sargassum would be compatible with these
fish, and more specifically about a Sargassum's characteristics.
<Comparable to other Xanthichthys spp. (using the genus to search for
information is worth a try) and in general rather docile (for a trigger)
and hardy. Crustaceans, clams and urchins may be eaten (most get along
well with them, though), larger fish are usually ignored. Beware all
triggers are personalities and may change their mind when becoming
adult. Your puffer is another species with a somewhat unpredictable
personality and it is hard to say for sure they will get along without
trouble long term. Another concern is that the trigger might bite the
fins of the shark. If you are lucky, it will work without problems, if
not… I would not buy this fish without another system or the option to
give it back.>
I purchased Axelrod's Marine Atlas (for 6$ on eBay, no less!!), which is
a fabulous book but very short in specifics on care, it is much more of
an identification book.
<Yes.>
The other book at the LFS describes the fish as reef safe and much more
compatible than other triggers. His jaw structure definitely looks
different than a 'typical' trigger like a clown or Picasso. I have not
purchased the fish, and maybe I won't at all, but it is certainly
tempting and I thought I might ask you guys first. We had the tank under
the quinine treatment for ick (still do, actually). The Powder Brown did
not make it, unfortunately, but all other fish are doing extremely well,
including the shark (and thanks again for the quinine info). I'm going
to continue the quinine treatment for the prescribed duration before we
think of adding anything.
<Good and good luck with your treatment. Be sure to let the system run
for a while even after the treatment to see if it worked properly before
adding anything.>
Thanks again. Thomas.
<You are welcome. Marco.>
Re: Sargassum trigger
comp.; Dog face puffer size follow up – 07/30/07
Marco,
<Thomas>
Fabulous stuff, thank you very much. Arothron nigropunctatus, in the
puffer ID section of WWM, is identical to my puffer. He may be closer to
5", realistically, but has been this length for years now.
<Interesting. Stunting and improper diet can probably be excluded due to
the large tank you have and the food you offer. I also assume/hope the
nitrates are permanently low given the other sensitive fishes. Aside
tank size, diet and water quality I cannot think of a factor, which
might stop the grow of your specimen. Possibly some issues in its early
life before you bought him.>
This is the one that bit my finger! Often times when I feed my shark at
night, I have to scoop him out of the way. As long as he doesn't think
my finger is food, he is docile, likes being rubbed, and eats out of my
hand. About 6 months ago I had purchased a tiny Picasso trigger, and the
INSTANT I placed him in the tank he attacked the puffer, so he was
removed and returned immediately.
<Another case of unpredictability. Some Rhinecanthus are quite docile,
this specimen not. A similar case cannot be excluded with the Sargassum,
but hopefully this time you are more lucky. I guess it will rather be
hiding for a while when introduced and not start attacking.>
He does receive a varied diet, of cocktail shrimp with Zoë, marine
cuisine, krill, and angel formula. He also eats his share of shark
formula, unfortunately.
<OK, good diet. The dog face puffers I know/knew personally which have
grown from 4 inches to almost 1 foot in captivity ate lots of mussels
and clams, because they seemed to like it and it abraded their teeth.
Could be worth a try in case you haven’t tested yet.>
He just has remained this size. I have no idea why. For a while he was
in an 80 gallon before the upgrade, but for most of the time he was
pretty much the only occupant. Anyway, thanks for the info. We won't be
adding the Sargassum trigger for a couple of weeks, while we observe the
system to make sure all of the ick was killed with the quinine. Thanks
again!
Thomas.
<You are welcome. Keep up the good work and enjoy. Marco.>

Crosshatch... trigger, Vlamingi tang incomp.
7/9/07
Hey guys, how's it going? Good I hope. So here's my question. I have a 155
bow front established for about 6 yrs. For the last 3 years I have 2 Vlamingi
Tangs
<Neat species, but need more room...>
and for about a year I have a male Crosshatch Trigger. They have all gotten
along very well. No problems during feedings or any other aggressive behavior.
Well yesterday I had the luck of coming across a female Crosshatch, she was
smaller than my male so I jumped on the opportunity to get her. Well so far they
are getting along perfect, but now the male crosshatch is acting very
aggressively towards the one Vlamingi. I can only assume that he is a male,
since they are both young there hasn't been any way to tell. My question is, is
this normal behavior for a Crosshatch or just one male showing his dominance to
another? And do you think it will subside in time?
Thank you.
Jay Uzzalinno
<These more open-water species are indeed territorial... and this is way too
small a space psychologically... Maybe adding a couple of "built up" arrangement
of rock ("bommies") will alleviate this agonistic behavior for a time... block
the line of sight... Pile them well, and high... to the surface if possible; and
either start saving for a much larger system, or plan to trade the Tangs in. Bob
Fenner>
I Want To Add A Bluechin Trigger (Not Enough
Info About Current Stock List) – 06/18/07
Hi there,
<<Hello there>>
Just a quick one. I have a Percula 120 (110gallon) bow front Aqua Medic reef
tank. In the tank I have 1 Comet, 2 Clowns, 1 Algae Blenny, 1 Yellow Tang, 1
Flame Angel, 1 Peacock Wrasse,
<<Several species with this “common” name...if this is ‘Iniistius pavo’ it can
reach 18” in length and though if feeds primarily on benthic crustaceans in the
wild, it likely will eventually consume some of your smaller fishes as it grows.
If this is ‘Cirrhilabrus temminckii’ then it will reach a much more manageable
length of around 4.5”...but without better/more info from you I can only
speculate>>
and 1 Dwarf Parrotfish.
<<Again, I have no idea what this is. I don’t recall ever hearing of a “Dwarf”
Parrotfish, nor can I find a reference. I can only hope this isn’t ‘Cetoscarus
bicolor’ or the Bicolor Parrotfish which is arguably the most offered/sold
Parrotfish species in the trade (as tiny juveniles) but is a bruiser that can
reach three-feet in length>>
In all about 35 inches of fish when fully grown (I think).
<<I hope this is not your system for determining how many/how much fish you can
put in this tank. The fishes must be evaluated on adult size, yes...but eighteen
2” damsels are much less burden on a system than four 9” fish would be...getting
the picture?. Do also take in to consideration the fish’s
temperament/compatibility/social interaction, as well as environmental needs
(type cover/substrate, water flow requirements, etc.), nutritional requirements,
et al>>
My question is, I would love to add a Bluechin Triggerfish, I have done my
research on this fish and it seems to be the best choice of triggers.
<<A wonderful aquarium species, agreed...but needs places to hide/sleep>>
They don’t get to big and are reef safe (ish)
<<In my experience, yes...and likely much more “reef safe” than that Parrotfish
you have>>
Do I have enough room in my tank and would it be ok with my current stock?
<<I’m inclined to say no...especially without better information on the fishes
you already have. Please write back to me with the scientific names of your
fishes (the Clownfish too) and I will be better able to help you>>
Thanks for all your help.
<<Quite welcome. EricR>>
P.S do these fish get to about 8-9 inches?
<<The Bluechin Trigger? Yes, this is likely close to maximum for many aquarium
specimens...but the species has the potential to reach a foot or more, see here:
http://www.fishbase.org/Summary/SpeciesSummary.php?id=6030 >>
Re: I Want To Add A Bluechin Trigger (Not
Enough Info About Current Stock List) – 06/18/07
Thanks for getting back, the scientific names are 1 - Calloplesiops
altivelis, 2 - Amphiprion ocellaris, 1 - Salarias fasciatus, 1 - Zebrasoma
flavescens, 1 - Centropyge loricula, 1 - Vermiculate wrasse (it was sold as
Peacock Wrasse) and the "dwarf parrotfish” is a Cirrhilabrus cyanopleura. Hope
this helps thank you.
<<Ah yes, what a difference a proper and definitive ID can make. This is a much
more suitable/proper mix of fishes than some of the “local common names” in your
original query suggested. Although, the Vermiculate Wrasse (Macropharyngodon
bipartitus bipartitus) is a decidedly difficult fish to keep and is not well
suited to your 110-gallon system (would benefit greatly from an inline
refugium). As for the addition of a Bluechin Trigger (Xanthichthys
auromarginatus), these are robust, heavy fish, but I think you could possibly
“just” squeeze one in...though this will definitely “fill up” this system and
preclude any other piscine additions, in my opinion. Regards, EricR>>
R2: I Want To Add A Bluechin Trigger (Not
Enough Info About Current Stock List) – 06/19/07
Thanks for all your help.
<<My pleasure>>
Just one more quick question.
<<Okay>>
Which would be best suited to my tank, Bluechin or a Pink Tail Triggerfish?
Thanks
<<I think it best if you stick with the Bluechin for your system. The Bluechin
is a slightly smaller species, and although there can be/are differences between
individuals, Xanthichthys auromarginatus seems to be a bit more peaceful than
Melichthys vidua (Pink Tail Trigger). Also, size for size, I feel the Pink Tail
Trigger needs more open space/water than the Bluechin for proper “social”
development. Regards, EricR>>

Blue-Throat Trigger Not Eating – 05/03/07
Hi folks,
<Hello.>
Great site, recommend it to whoever will listen.
<Awesome.>
I have a question about a blue-throat trigger.
<...One of my favorites...>
This is my second attempt at one of these fish and it is getting
frustrating.
<Well lets see if I can help you out.>
For the record I have been keeping saltwater
fish for over 15 years and this is my first attempt at a triggerfish. I
have a 5 year old majestic angel, a 7 year old swallowtail angel and a 7
year old Naso tang along with a few little guys to keep things hopping
presently in a 90 gallon reef,
<A bit on the crowded side but okay...>
all are happy and fat with no aggression but now I figured I could try
something new. The first trigger died due to a
bacterial infection that I couldn't get to in time but this second one
is not visibly sick but still won't eat.
<Blue throats tend to be a little more flighty/finicky...in general
exhibit behavior atypical of how would expect a tiger to act. How long
has it been?>
He is about 3" long and in a 30 gallon quarantine tank with a few chunks
of live rock, a skimmer, power head
for movement and an AquaClear 500 hang-on filter. There are a couple of
other fish in there, just to keep it cycled. I have checked all the
normal
water parameters, all is fine. I have tried PE mysis, smaller mysis,
flake,
bloodworms, shaved shrimp, squid and clam - won't touch anything.
<Wow, you have pulled out all the stops. I have a few more suggestions
though; market scallops or mussels soaked in a nutritional supplement
like Selcon.>
Is the quarantine tank too small ?
<No seems adequate...for a quarantine.>
The quarantine tank has had a small
Pseudochromis and a coral beauty in it for a couple of years until
recently when I nicely took a marine Betta because he had lateral line
and Lymphocystis.
<Mmmm...with all these animals, yes quarantine tank is too small,
quarantine tank should be just that....quarantine.>
He has since been cured ( yes the lateral line too ) but I
don't really have any place to move him so he is in the quarantine
too. Is he intimidating the trigger ?
<Perhaps, the specimen I have is extremely flighty; easily scarred.>
There seems to be no aggression between the
two, in fact they use the same cave at night. Any ideas would be
great. I
would hate to lose the trigger because of a screw up on my part. I
intended
to move him into my 90 gallon reef after his quarantine period, which
has been about 3 weeks. But I don't want to do that if he is not eating
because he will never get food in there with my other fish.
<Rob, how long has it been since the fish has not eaten?
Thanks for your time,
<Anytime...I look forward to your reply.>

Re: Blue-throat trigger STILL not eating – 05/03/07
Hey Adam,
<Welcome back Rob.>
Thanks for the reply.
<No problem.>
I have not seen this trigger eat in 3 weeks.
<Mmm...that is a little lengthy.>
He doesn't seem to be losing a lot of weight but I can't figure out what
he is eating.
<This tank has other animals, how well established is it? Perhaps
micro-crustaceans.>
I have soaked all of the food offerings in Selcon. ( been using
that stuff for years )
<Cool.>
I ended up putting the trigger into my 90 gallon reef last night. He
hid for around a half an hour and then started exploring the tank.
<A good sign, mine is till rather reclusive almost a year later.>
My majestic wasn't too happy but he got over it quickly. I added some
mysis and blood worms hoping that he might get the feeding idea from the
feeding frenzy that occurs every time I put anything edible into that
tank. Nothing, in fact he hid. He does seem to be more active in the
larger tank but I want him to eat soon.
<I understand, I would also try to offer food just after the lights go
off...in his direction with a turkey baster if you can get hold of
one.>
I am assuming that he will figure it out any day now, he has got to be
hungry and with the other fish active and feeding, he has got to get
it. I have had other fish not eat in the past, but they didn't live
this long or I figured out what they wanted. I do not want to lose this
fish, he is way too cool looking. Do you think I should just wait it out
or should I take him back to the LFS?
<Well I would ask the LFS what they were feeding him.>
To be honest I don't know how much effort the LFS would put out for a
fish that won't eat.
<Not much.>
Do you think I need to increase filtration?
I have a red sea skimmer, Fluval 404, a large emperor hang-on, UV
sterilizer ( 15w ),
3 powerheads and about 95 lbs. of live rock and an inch of live sand.
<Well I'm not a fan of canister filters on marine tanks, I prefer
macro-algae refugiums.>
So far I haven't had any big problems at all, at least for the last 3
years.
Any advice would be appreciated.
<A few more feeding suggestions, if an LFS has live brine or live
mysids.. give them a try. I know that live brine and live foods aren't
the best thing. and certainly not a long term option but it's better
than nothing. Also try some meats that are more poignant to the sense of
smell, mackerel, squid, along those lines.>
Thank you,
<Welcome.>

Adding another fish, Blue-jaw Triggers (Xanthichthys auromarginatus) -
02/06/07
Hi Bob and crew.
<Crew here! Mich with you tonight!>
I have a 125G FOWLR and some polyps. About 100-125 lbs of live rock.
I have one Red Sea Sailfin Tang (4in)
one Scribbled Angel (3-4in)
one Cinnamon Clown
one Christmas Wrasse
One See-through Goby
one Green Mandarin
six Yellow Tail Damsels.
My fish are doing great, but I have always wanted a trigger. My faves are
Clown and Picasso but I don't want to risk their aggression. I have settled
on the Blue-jaw. I do have two
reservations. One, I think my tank may be overstocked with the addition of
the trigger.
<If your nitrates aren't already elevated, I think this would be a fine
addition.>
Two, I have read that they are very easily frightened and spend a lot of
time hiding.
<Blue-jaw Triggers (Xanthichthys auromarginatus) can be a little shy and may
spend a good deal of time hiding when they are first introduced, but
typically come around to become a more social member of the community.>
I wouldn't want to add a fish that I will rarely see.
<Understandable. May be a problem initially, but I think in the long term
will be ok>
What do you say?
<Hey! Hey! This was made in the USA?>
Thanks
<You're welcome! -Mich>
P.S.,
If you think the trigger is a bad idea, what fish would you recommend that
will fit well into my community, or am I done?
<I think you have made a good choice!>
Adding another fish, Blue-jaw
Triggers (Xanthichthys auromarginatus) 2/7/07
<Mich here again!>
Thanks again for a timely reply.
<Welcome!>
You guys are great.
<We try.>
If I do end up adding the trigger, can I add anymore small fish, and if yes,
what would be your choices?
<I would proceed slowly here. Take one thing at a time. Add the trigger and
see what happens. You don't want to push your filtration or psychologically
crowd the tank. With any possible future additions I would be thinking about
where the fish tends to spend its' time, i.e. is it a swimmer, a bottom dweller,
a percher etc., behavior type issues. Look at the typically behaviors of the
other fish in your system and think about where a small fish might fit
in. Don't forget about compatibility issues here also. You don't want to
provide live food in this instance! Patience here my friend.

Sick Trigger (Xanthichthys auromarginatus) – 01/17/07
Greetings,
<<Hello!>>
First, I want to thank you for the work your doing helping us make insightful
decisions.
<<Most welcome...truly a pleasure to share>>
I have a Blue Jaw Trigger, Xanthichthys auromarginatus,
<<Me too!>>
that has not been well for two weeks; it is very immobile, propping himself up
on or over something continually.
<<Hmm, it's not unusual for this fish to occasionally stop roaming/peer out at
the world from its favorite cave...but it shouldn't be lying around all the
time>>
He has been eating, but only when fed directly and does not seek food.
<<Mmm, should be active/interested at feeding time>>
A couple of days ago he began spitting back out the large plankton, so I made a
batch of food in the blender of: shrimp, oyster, clam, Selco, formula II, and
daphnia; it is eating, but again only when basting directly toward his
mouth. The fish’s colour is about a six out of ten; there is yellow outlining
the tips of the fins with a dark band on the body at the fin's base.
<<The yellow margin on the fins is naturally occurring on a male X.
auromarginatus...but the dark band is possibly a sign if distress>>
Its distinctive dots and blue jaw are still clear.
<<Good>>
I QT’d the fish. He was housed with a Sebae and its GSM since May (8
months). The tank is too small; it is a 70-gal bow front and has four feet in
front and back of the rockwork to swim with two or three nice caves underneath
in which he'd sleep. Many sites put the limits for this fish at 75 gal, and I
knew Bob recommends at least 100 gal.
<<Yes...or larger>>
Occasionally needing to keep the money maker happy I ordered the fish. There
are no signs of trauma, or tumor. Are these symptoms of small tank syndrome or
something recognizable/treatable?
<<If the fish has not suffered some physical trauma, then this sounds to me like
an internal protozoan infection (lethargy is a telling symptom here). These are
difficult to treat, and often by the time the symptoms manifest it is too
late. The fact the fish is still eating is a good sign and I suggest you try
some foods post-haste made for treating internal parasites (New Life Spectrum
has such a food).>>
My wife is a veterinarian having many medications/antibiotics available.
<<Then perhaps try soaking some thawed frozen food (mysis shrimp, chopped krill)
with Metronidazole. See here for information on dosages, cautions, etc. :
http://www.wetwebmedia.com/metranidazole.htm >>
Lastly, I’ve read to moderate length about hyposalinity, and while probably not a
cure, will reducing salinity ease fishes’ metabolic demands?
<<Though it can be of use in some situations (dips/baths), I am not a fan of
long-term hyposalinity for the “stress” it places upon the fishes. They have
evolved to live within certain saline parameters, changing those parameters
requires them to make adjustments/work harder to maintain their osmotic balance
>>
I maintain a salinity of 35ppt.
<<Excellent...do keep it there>>
Thank you,
Robert
<<Good luck Robert...and please let me know how the treatment goes. Eric
Russell>>
Last Fish...(Not The Best Choice) – 01/11/07
Hey Guys an Gals,
<<Cheers David!>>
My wife and I have a 50 G tank with several corals and 3 small fish. 1- Galaxea
(yes I know all about the sweepers) got it cheap and it might be moving out in
the near future for trade.
<<Mmm, yes...a very aggressive genus with a very strong “sting”>>
Has whole left half of aquarium to itself.
<<Indeed>>
Q: what is the proper item(s) to feed this coral??
<<Minced meaty marine foods, small mysis shrimp, Sweetwater Plankton,
Cyclop-eeze...a mixture of these>>
Looking on WWM using Galaxea as a keyword I only find tentacle warnings.
<<That’s about to change [grin]>>
3- Ricordea Yumas have center of tank, placed a full 11" away from Galaxea.
<<Wise...though the Ricordea can be quite nasty itself>>
1- LT plate coral far right side of tank on sand bottom.
2- Sarcophyton one 1" frag one 4" frag mid-level right side.
<<Keep in mind these can/will grow large (some to a couple feet in diameter) and
are quite noxious>>
I use a Coralife lunar light. 1-96w compact fluorescent. 1-96w actinic and 2
small blue
LEDs. I keep 10000K on 9hrs, actinic comes on one hour before and stays on one
hour after. Blue LEDs are on at night. Is this lighting enough for what I’m
keeping?
<<If the bulbs are close to the water and changed out regularly...just barely I
think. The addition of another 10000K bulb (even a smaller wattage, say 65W) is
warranted here in my opinion>>
I have two powerheads for movement one PowerSweep 228 and a Whisper 660.
<<Another powerhead would not hurt either>>
Use a Magnum H.O.T. 250 for carbon/phosphate remover.
<<Excellent>>
Running a Coralife Super Skimmer 65g which IMO works awesome, at least one inch
of "nasty" in collection cup daily. I had convinced myself that my fancy for
trigger fish was not to be exercised until I read "Have you overlooked these
fish" by Gregory Schemer in the 2006 annual Marine Fish and Reef
magazine. After reading that article I have read everything I can on the Blue
Throat triggerfish.
<<An excellent species for reef tanks (have on in my reef), though I consider
your tank too small for the long-term health of this fish>>
My tank has a Tomato clown that I have had for 3 yrs and is only about 2 1/2 "
(the alpha fish in this new 50. He has been in for a month now). I added a
Firefish and Falco Hawkfish the same week I added the clown.
<<Kudos on the choice of Hawkfish...a small species (to about 3-inches), and
attractive too>>
Almost two months have passed. Everyone eats fine. Firefish is NOT afraid of
"Hanging with the big boys" and eats as well as the clown.
<<Good to hear...these shy fishes are often easily bullied to the point of
starvation>>
I just went by the LFS and there Screaming "buy me !! buy me !!" is a very small
Blue throat, 3-inches.
<<Uh-0h>>
Now, I had already been doing the research and I’m convinced that everything in
my tank should get along with some warnings of course. And this 3" specimen
really seems to be "the one last fish" ha ha hopefully. j/k
<<Mmm...>>
I had the store put it on hold. I got a week to talk myself out of it. Can you
help talk me INTO it?
<<I’m sorry to disappoint you...though it may not seem so now, your tank just
isn’t big enough (should be at least twice its size) for this large (grows to
more than a foot), robust and active fish. Many things affect the
nature/behavior of fishes in captivity...and in my opinion an all too common
practice in our hobby that mal-affects fishes more than many realize is placing
them in too small volumes of water. The argument that “I’ll upgrade when it
gets too large for the tank” holds little weight as the fishes often develop
behavioral disorders/develop health issues from the “growing up” in a too small
system...not to mention these “promises to upgrade” rarely pan out for a myriad
of reasons>>
Ya think this fish will co-exist?
<<The tankmates are fine...it’s the housing that’s inappropriate I’m afraid>>
I have some small crabs, snails and such, and a sea hare that shows himself
seldom (know about the possible ink too). I am not worried about the clean up
crew; they can be replaced if they disappear although I have read they will most
likely be safe from the trigger. My wife said "You know that’s the last fish
right?" She reads WWM too.:)
<<Best to make it an appropriate selection then>>
Please help us with our decision.
<<I’ve given you my position on the matter...not what you wanted to hear I’m
sure...but truly best for the trigger in my humble opinion>>
David Conway
<<Regards, Eric Russell>> |
Re: Last Fish... (Not The Best Choice) –
01/12/07
Thank you for your quick response Eric,
<<Quite welcome David>>
I should have told you more but my wife says I’m too "wordy."
<<Ah...but tell here the more I/we know the better we can respond>>
This 50 gallon tank was going to have a 20 H refugium added (we have 6
tanks in the house).
<<That’s excellent...but doesn’t change my mind re the triggerfish>>
The 20 was one of two tanks I combined for the 50. After reading I
kicked myself for buying the fifty not drilled and setting it up anyway.
<<Utilizing the old siphon overflow eh?>>
My plans of turning the 20 that is now my quarantine tank into a
refugium really don’t work unless I want to go the overflow box way, not
to mention it’s downstream.
<<This is not a problem really/should not keep you from employing the
refugium>>
Among others we have a 125 drilled tank in our basement that we haven’t
gathered enough supplies or live rock for (the fifty gallons is holds 75
lbs or so).
<<Aha! This would be a MUCH better proposition for the Blue Throat
trigger...and as long as you can make some hiding places and a “cave”
for the trigger to sleep this amount of rock may be fine as well. I
prefer to use a minimalist approach to placing live rock in a reef
system. It doesn’t take as much rock to provide sufficient
bio-filtration as those selling the rock would like you to believe. Not
to mention you also give your fish more room to swim and both fish and
corals more room to grow. And honestly mate...a tank with less rock and
large full growing corals looks much better than a tank full of rock and
a bunch of stunted frags>>
This fifty is NOT our last tank by no means and I agree I’ve read about
juvenile Blue Throats in no less than 40 and the appropriate size for a
larger one would be 75-100G
<<Or bigger...yes>>
I WILL have a larger tank --just gotta get the wife to imagine that
empty tank in a cleaned out basement office };->
<<Perhaps a nice bottle of Shiraz will help...>>
So If I get off my butt and do something with this larger tank, which
I'll do slowly, then how long would a "conscientious" aquarist be able
to keep a 3" B.T. Trigger in a fifty
gallon tank before he grows any "fishy" behavior?
<<Mmm...a truly “conscientious aquarist” would setup/establish/mature
the larger tank “before” making the purchase. But since you already
have the tank on hand (please don’t make me regret this David), three to
four months would probably be ok. These fish are slow growers and you
likely won’t notice much change in its size in that time, but that
doesn’t mean you can leave it longer...get that 125 up and going>>
On another note I still want to add water volume to this fifty, is it
worth it to have a downstream refugium?
<<Indeed it is...I have a 55g downstream refugium (empties to the pump
chamber in my sump) on my reef system>>
Will anything alive make it to the main tank?
<<It will...impeller-shear is an overrated concern...most of the
beneficial organisms generated by the refugium will make the trip to
through the pump just fine...and even those few that might be damaged
will still provide a beneficial treat>>
And what would be the best way to turn an established tank into a
refugium without completely emptying tank and fowling the already 3 yr
mature sand bed?
<<Several ways methodologies could be employed. The simplest would be
to add some coarser substrate/live rock rubble and culture the myriad of
micro- and macro-fauna that inhabits such...another option is to add
some lighting and place a bit of macro-algae (my preference is
Chaetomorpha for its “user friendliness” and its dense matrix which is a
perfect environment to culture worms, amphipods, mysids, and associated
epiphytic matter) above the sand bed to grow/compete with nuisance alga
for nutrients>>
Can I empty it down to the sand bed and dry the sides inside enough to
glue in partitions?
<<Probably...or maybe check out the article from one of the earlier
editions on our on-line magazine where it is shown how to make install
“removable/adjustable” baffles using weather-stripping to hold them in
place>>
Or is it even worth the time?
<<Well worth it, in my opinion>>
Oh yeah, the LFS that has the trigger is one of the most knowledgeable
stores we frequent. They can be more expensive so we usually go there
for learning purposes and most of the time the guy who runs the fish
room talks me out of stupid moves.
<<Good to hear>>
I’m surprised he hasn’t stopped me from wanting this fish.
<<Mmm...>>
He has seen my tank and he even has the Blue Throat in a fifty gallon at
the store. Now what’s up with that?
<<Differences of opinion maybe...coupled with the fact that
retail/transient facilities have different considerations compared to
hobbyist aquaria>>
Heck, he has even said to me (when my wife wanted a frogfish a year ago
and wanted to know the price) "For anyone else $75, for you’re tank
199.99 !! " He knew I knew better and he knew my wife wasn’t “reading
up".
<<Ah...then good for him>>
This fifty is the largest tank I have running as of now, and as our
passion for this hobby grows so have our tanks. 6 tanks was a crazy
chore on weekends and this all started with removing some big Aiptasia
from a 36 bow. Now we got a species specific tank for "naughty rocks" a
larger one to eliminate two was smart move, now we still have 4 to
combine. I have so many glass boxes downstairs full of old powerheads
and lights, God help me if she ever sees a waterdog or something "cute"
like the frogfish. If we can’t mix it in "we could always start another
tank," Doh!!
<<Ah but you have a “problem” many, many hobbyists would like to
have...a spouse that allows more than one tank in the house!>>
After a trip to the fish store I’m happy to afford a Hacker Schorr or
two.
<<Indeed...do be careful not to cut “too deeply” in to the beer budget!
[grin]>>
I'm rethinking the B.T. even though I know this 125 will happen someday,
Hell it’s there waiting. All my friends will love coming over and
sitting on boxes and old junk to look at the new tank in the
basement LOL
<<If they’re pet-fish folk they won’t mind>>
Thanks for your time Eric; I seemed to have time enough to get "wordy".
<<No worries mate...and it’s been a pleasure to share>>
Oh here’s a pic of the tank.
<<Ah yes...is that a Rhodophyte at the upper right? Very nice, Eric
Russell>> |
|
R2: Last Fish... (Not The Best Choice) – 01/14/07
In that pic the upper right contains "red grape Caulerpa".
<<Mmm…okay>>
And just to the left of it is my small Sarco frag. The Caulerpa has
been moved to the far left behind the rock under the PowerSweep (figured
the Galaxea wouldn’t sting it) and the larger 4" tall Sarco frag has
been put in its place on the mid-level right. No worries on size
here...Have read enough on the propagation of Sarcophyton that the 4"
will grow another 2" if it’s lucky before I try the doughnut or pizza
method of fragging.
<<Ah…yes>>
Speaking of fragging... We go to a monthly fish club at that same fish
store.
<<Neat>>
I always see frags I haven’t read up on for free or for trade. In the
past I have asked if I could get a small list of compatible corals for
my wife’s nano reef. She keeps several little Kenya tree frags, one
bigger Xenia frag and of course she has a small Sarcophyton no bigger
than a pencil eraser. She obviously likes "dainty frilly things" and
I’m not sure what to research. Can you give me a list of maybe 3-5
different things she could add without toxin or size problems?
<<Hmm…pretty much impossible to meet those criteria. There are many
possibilities (on a small scale), as well as many possibilities for
things to go wrong very quickly in these small volumes of water. I am
not a fan of nano tanks…but…these small reefs do seem to be popular and
to be fair I have seen a few that looked quite nice…for a time. As for
stocking/maintenance/et al of these systems do start reading here (http://www.wetwebmedia.com/smmarsysstkgfaqs.htm)
being sure to follow the associated links in blue at the top of the
page. This will afford you much more/broader info than I can share on
this topic>>
I went to look at the trigger again, Joe reminded me that all their
tanks are 50 G size, except for the "show" tanks and "Q" tanks are
sharing a 4500 gallon system and the fish get moved every few days to a
different tank to avoid dominance issues.
<<Mmm, this seems overly stressful to me…but just my opinion>>
The BT trigger is really about 2" now that I can see him not locked in a
hole.
<<Pretty small…better to acquire in the 3” – 4” range…and preferably a
Hawaiian specimen when possible>>
He is in the fifty with a 7" pink tail trigger and two Hawkfish bigger
than my Falco and bigger than him. I didn’t get the chance to stay an
watch him eat.
<<Would suggest you do so…this fish “can be” problematic to get to
feed>>
DAMN I had to open my big mouth and question what could have been a
really cool although dumb, impulse buy :) :/
<<Ah but Dave…you knew it was the right thing to do. The fish, you, the
hobby in general is better for your effort>>
Now I’m afraid my clown might even kick his ass.
<<This has crossed my mind as well. Clownfish become very
territorial/aggressive (they are a damsel, after all)…in fact the only
fish to ever attack/draw blood from me in more than 30 years in this
hobby has been…you guessed it…a clownfish…>>
The clown is close to two months in and is starting to show dominance
over the side of the tank with the plate coral. Passers by get followed
away, not chased yet.
<<Likely to become more overt/physical in its actions>>
Firefish has been moved to one of the nanos simply because the wife
wanted it originally.
<<Hmm…and one of the few fish suited to these tanks>>
I'll still wait the LFS’s' quarantine out before I tell him I don’t want
the trigger.
<<Decided to wait until you can provide a proper home have
you? Excellent my friend>>
Thanks again,
Dave

Questionable Aquarium Service...Trying To Do
What's Needed - 09/22/06
Dear Wet Web Crew,
<<Hello>>
My employer has a beautiful 200-gallon salt-water tank, and has a tank
service that comes in and cares for this tank.
<<Ok>>
I have a serious lack of confidence in this company because I did a
little research on your site and they have made many really bad
mistakes.
<<Some do yes, but doesn't mean this one is "bad". Have you been able
to talk to other/previous customers of this company? Have they done
anything to make you feel uncomfortable with their level of service?>>
First, they got the chemicals wrong in the tank, which killed most of
the fish.
<<Ahh...I see...sounds like you may have good reason for your
concerns...>>
Then, when they replaced the fish, they brought us 5 crabs, a
blue-throat Triggerfish, 3 assorted angelfish
<<Mmm...>>
(in separate bags. NOT introduced at the same time), and a pair of
ocellaris (among others). Of course, the Trigger ate the crabs
immediately. I am an administrative assistant with little/no knowledge
of fish, and have been tasked with taking care of their diet, and making
sure they get what they need.
<<Sounds like you need to start doing some reading/researching my
friend. Google searches on our site and the NET re the species names
will yield much information>>
So I need a little advice from professionals that actually care about
the fish. After the initial eating of the crabs, and the disappearance
of one of the smaller Angelfish (which after reading on your site I
found out why <<...?>>), the blue-throat trigger has started exhibiting
odd behavior. He lies down at the bottom of the tank on his right side,
and just lays very still for long periods on time.
<<Maybe not all that "odd" after all. Is there live rock in this tank?
(should be if there isn't)...Does this tank have any type of decor/rock
work? These triggers will very often "rest" in a hole or crevice in the
reef during the day, and definitely at night. If the tank is not
suitably aquascaped the trigger may be merely "resting" on the bottom of
the tank>>
He is still eating well (They get frozen shrimp, the cubed kind once a
day, and Formula 2 the blue-green algae variety flakes twice daily).
<<Do look in to obtaining some New Life Spectrum Marine pellets and a
frozen "Angel" food formulated specifically for their care. Feed these
AND the frozen shrimp, with the flakes, twice daily>>
His color has faded a bit, but he doesn't have any spot or slime on him,
and he hasn't rearranged the tank in a while- he used to do that all the
time. I read one of your entries about one having similar behavior in a
20 gallon tank, and you said the tank was too small but I don't think
that is the case here- the tank is
200 gallons.
<<Agreed...but that doesn't mean there aren't more/other environmental
factors at play here...such as water chemistry or the "design" of the
tank itself>>
Could he be malnourished or ill?
<<Maybe...the trigger needs several small feedings of meaty foods
daily. The Spectrum pelleted food and the frozen shrimp fed at least
twice a day will help. For even better nourishment of ALL the fish,
consider getting/soaking the food in Selcon and/or Vita-Chem a couple
times a week>>
And is there some product or variety of food I should tell my boss to
get for him?
<<Ah yes!...as explained>>
Cordially,
Jane
<<I want to help Jane, do write back if you need further clarification
on anything...and try to give me as much information about the system as
you can (filtration/maintenance/aquascaping (or lack of),
etc.). Regards, Eric Russell>>
Re: Questionable Aquarium Service...Trying To Do What's Needed – 10/11/06
Dear Eric,
<<Hello Jane>>
I just wanted to thank you for your excellent advice.
<<Was my pleasure to provide>>
It has been about two weeks since you emailed me with the suggestions. We
invested in
New Life Spectrum Marine Pellets, and we also purchased a lot more coral
decorations to go on the live rock.
<<This pelleted food is an excellent staple for your fish>>
We hired a company to change out the coral and clean the tank/maintain the
filtration system every two weeks.
<<Excellent...but I do hope you/someone “monitors’ the tank on a daily basis>>
They have been instructed to bring in lots of smaller shells and other such toys
for the occupants.
<<Mmm...do be careful not to create detritus traps>>
Our Bluethroat Triggerfish has perked up considerably; I think he may have been
suffering from boredom.
<<Indeed...these are intelligent and personable fish...and somewhat “shy” at
times. It’s never good to place fish in a “plain glass box” devoid of proper
structure/hiding places...is very stressful>>
All the fish seem to be a little brighter and a lot more active.
<<Good signs>>
Thanks again for your excellent advice and support.
<<I’m glad it proved useful...thank you for the follow-up>>
Peace and Blessings,
Jane
<<Regards, EricR>>

Mating of the Sargassum and Crosshatch Trigger 10/2/06
We Have a Sargassum Trigger (Which we thought to have been a male because
of the red tail.) The past week our Crosshatch has been acting strange, digging
out sand from the bottom of the tank and losing all of his colors for about 2-5
minutes then getting it back. Today we noticed that the Sargassum's lower
stomach is huge and the opening which I believe are where the eggs come out is
dilated (white around it like tearing). Is there a possibility that the
Sargassum that we thought was a male is pregnant and actually a female.
<Yes>
Can't find out much information on the Sargassum sex or how long they carry
their eggs.
Please Help

Finicky Sargassum Trigger – 09/23/06
Hello from Alabama,
<<Greetings from South Carolina>>
Thank you for the wonderful site and all of the great information, my tank has
improved greatly after implementing many of your ideas over the past year.
<<Is a collective effort...you're quite welcome>>
I do have a question that I couldn't find much info on though. I purchased a 5"
Sargassum Trigger one week ago, I had a problem with my quarantine and after one
day I had to put it into the main tank ( a 265 FOWLR). The fish looks great and
is very active, which surprised me because I have a Blue Throat Trigger that hid
for the first several days, but now swims constantly. I assumed this fish would
do the same.
<<Indicative of the difference in species/personality>>
Even though it is active it hasn't eaten anything this whole week.
<<Troubling...even more so if this fish has not eaten since capture. Did you
see the fish eat at the LFS before purchase?>>
I have tried pellets, flakes, frozen shrimp, frozen Mysis, and even live guppies
and ghost shrimp.
<<Hmm...is a planktonic feeder...though according to FishBase they will also
dine on crabs and urchins>>
It doesn't show any interest in food at all.
<<Not good>>
Do you have any ideas of what else I could try and do you know how long he can
go without eating. Any help will be appreciated.
<<The fish can go a surprisingly long time without feeding, but not eating for
more than a week becomes worrisome. If the problem were internal parasites I
would expect the fish to have expired by now...the fact that it is still alive
leaves "some" hope that this is a problem of acclimation/finding the right
stimulus to get the fish to feed. Perhaps you could try some fresh
mussels/clams/oysters on the half-shell from your local grocery store. I have
had success in the past getting finicky feeders to eat by offering (thawed)
frozen glass worms (mosquito larvae). Try soaking these in Selcon for a bit
more enticement/nutritive value. Another food you should try is Sweetwater
Plankton. This small soft bodied food (Daphnia actually) is a great "plankton"
food. Both of these will likely be appreciated by the Blue Throat as well>>
Thank you,
Jeremy
<<Good luck. EricR>>
Re: Finicky Sargassum Trigger (Refugium Plumbing) – 09/28/06
First of all let me say thank you for your help with my triggerfish, the
night I received your response he began eating the Mysis shrimp.
<<Ah, super!>>
He now will eat anything, but I am still trying to find the zooplankton since
that is what they are more accustomed to.
<<The Mysis are a good “staple”, but varying the diet is always better. Both
the Sweetwater Plankton (saltwater formula) and the New Life Spectrum pellets
should be easy to find at many of the on-line vendors>>
I now have another question.
>>Okay>>
I have been struggling keeping my nitrates below 20 ppm and I would like to be
able to culture some copepods and things so I have decided to add a refugium
after reading all the good reviews on them.
<<Indeed...a very worthwhile addition to any system>>
I have a 265 gallon tank with a sump and an AquaC EV-180, and about 150 lbs of
live rock. I have a 40 gallon Oceanic Trickle filter I am not using that I
wanted to try and convert to a Refugium. I have attached a drawing of what I
have in mind.
<<I see it>> <Graphic not pasted here for space/dnld considerations... see
Refugium Designs... RMF>
My problem is that I am very restrained by the size of the stand I have and the
space that I have.
<<A very common tale>>
Most people seem to have the space/height to drain from the tank to the 'fuge
and then down to a sump. I will have to have my sump and 'fuge on the same
level with only about 2" height difference in the two.
<<Could be fine...do ensure there is enough “empty volume” left to handle the
transient water volume when the pumps/power go off>>
My plan is to have water flow from the tank to the sump and the 'fuge and then
the 'fuge will overflow into the sump and be pumped back to the tank.
<<That’s how I do mine (375g display, 75g sump, 55g refugium)>>
From experimenting in my garage I think I can only put about 150 gph through the
'fuge this way to keep it from overflowing (of course I could have powerheads in
the 'fuge for better circulation in there).
<<Flow-rate is determined by the size/number of throughputs...but 150 gph
through this refugium should do fine>>
I thought of adding another overflow and pump, but besides the added cost, I was
afraid that would be too many variables (as far as keeping the system from
overflowing), but maybe I am wrong.
<<All comes down to not spilling more water in to the refugium than you can
spill out of it in the same amount of time.
I guess my questions are do you think the 150 gph would be enough for my tank to
see a real benefit, and looking at the picture can you suggest a better way to
get water through the fuge and to the sump.
<<An emphatic “yes!” to the first...and as for the second, I suggest you add a
gate-valves to the pump output and to the refugium input to allow for flow
adjustments and be able to “shut-off” the refugium for maintenance. And if
these are “hard” connections, you may also want to consider installing unions>>
Sorry for the length of the email, and thank you in advance for all of your
help.
Jeremy
<<No worries Jeremy, am happy to help. Regards, EricR>>

Funny Trigger Story - 09/23/06
I just moved my three-inch male Blue Throat Trigger from quarantine to the
display tank 24 hours ago, and he has remained hidden in a nook in the rockwork
of my 90 gallon tank ever since.
<<Not unusual...can be rather shy/timid as triggers go>>
I’m not worried about him. He acted the same way in quarantine for the first
three or four days only to come out and be friendly for the following month.
<<Indeed>>
I have two RBTA (a recent split), a B/W Ocellaris Clown pair, a Twin-spot
Hogfish and a small Wheeler’s shrimp goby that hasn’t found his pistol shrimp
yet. I have probably twenty snails, two large cleaner shrimp, one hermit crab
and one small porcelain crab that came with some live rock, all running well and
getting along for the past seven or eight months.
<<Excellent>>
Anyway, the trigger has taken up residence in the same cave as the porcelain
crab.
<<The porcelain crab hasn't taken up residence in one of the anemones?>>
Now here is the odd thing. The crab, which can’t even be an inch long, seems to
be trying to bully the trigger out of its hiding spot.
<<Amazing creatures we keep, eh!>>
They seem to have come to an arrangement and aren’t bothering each other at the
moment.
<<Ah, yes...and will likely cohabitate just fine>>
I just thought y’all would like to hear about a tiny crab picking on a trigger
that is probably twenty times his size. Thanks y’all for the wonderful work you
do. My fish and I owe you for all of your great advice.

<<Were pleased to be of service...and thank you for sharing. EricR>>
Another Reef Tank for a Bluechin Trigger - 07/27/06
Hi Crew,
<<Hello Jeff>>
I have a question about the stocking of my system.
<<Okay>>
I would like to add a pair of Bluechin Triggerfish (Xanthichthys
auromarginatus).
<<Wonderful fish! I introduced a pair to my reef tank a couple years
ago...sadly I've since lost the female, but the male is doing great>>
But I am not sure if they will put me over the bio-load that my tank can handle.
My current system configuration is as follows:
-450 Gallon Reef Ready Custom 96" x 36" x 30" display tank.
-Euro-Reef CS 8-3+RC Skimmer and a Deltec APF600 Skimmer
-63 gallon sump, 55 gallon Refugium and 39 gallon rock Refugium
-2 Tunze 6000 Streams & 2 Tunze 6100 Streams
-Lighting: 3 250 watt MH HQI and 4 39 watt actinic T5's
-145Lbs Tonga Rock, 84Lbs Base Rock, 16Lbs Tonga Branch Rock, 60Lbs Indo Rock,
and 60Lbs of Marshall Island rock
-420Lb Bioactive Live Aragonite Reef Sand
Current Bio-load in tank:
-Various Soft Corals, LPS, Zoo's, mushrooms and Clams.
-Also various crabs, snails and shrimp.
-8 Zebra Dartfish (Ptereleotris zebra)
-9 Blue-Green Chromis (Chromis viridis)
-1 Green Mandarin (Synchiropus splendidus)
-1 Scooter Dragonet (Synchiropus ocellatus)
-1 Sailfin Tang (Zebrasoma veliferum)
-1 Mimic Tang (Acanthurus pyroferus)
-1 Comet (Calloplesiops altivelis)
-3 Ochre-striped Cardinalfish (Apogon compressus)
-1 Pajama Cardinalfish (Sphaeramia nematoptera)
-1 Copperband Butterflyfish (Chelmon rostratus)
-1 Orchid Dottyback (Pseudochromis fridmani)
-2 Percula Anemonefish (Amphiprion percula)
-1 Ornate Wrasse (Halichoeres ornatissimus)
-1 Twinspot Hogfish (Bodianus bimaculatus)
-1 Flame Wrasse (Cirrhilabrus jordani)
<<Hmmm...but for the Sailfin which will get quite large, and the Comet which
will be of moderate size (Mimic and Copperband to a lesser degree), most
everything else is fairly small. Considering the size of this system, the (2)
quality skimmers, the presence of a large sump and refugium, and plentiful
though not "overdone" live rock...I would be tempted to add the triggers>>
Thank you in advance for any advice you can provide.
<<Try to get Hawaiian specimens if you can. And make sure you acquire both the
male and the female at the same time (in the same shipment even) to lessen the
possibility of conspecific aggression. When feeding, small portions of meaty
foods (mysis, plankton, glass worms...all with a twice-weekly soak in Selcon)
fed a couple to several times a day are best. Mine even enjoys New Life
Spectrum pellets...which do a fabulous job of soaking up Selcon/vitamin
supplements. Oh yeah, a cave/crevice (one for each) in which to hide/watch you
move about will be greatly appreciated by the triggers>>

Trigger Update and Some New Questions...Stocking/Compatibility - 08/06/06
Hi Crew!
<<Howdy!>>
First, I have some good news to report: Our blue throat triggers that we wrote
about a while back are now in the main tank (for the past two weeks) and seem to
be doing really well.
<<Yippee!>>
The fish seem happy and are very active, eat like crazy and don't bother their
tank mates. Yeah! (Thanks again Eric R. for all of your help!)
<<Hee! Tis me again! ...and you're very welcome!>>
Now, for the new issue:
<<Okay>>
Long story but it ends like this: Someone had a reef tank that completely
crashed and they were unable to care for the fish (tank was without circulation
for almost 24 hours, temp at 92 F, two dead fish in tank which probably raised
the ammonia).
<<Only two?>>
So, we rescued the remaining (barely) live fish and put them in our Q-tank to
see if they would recover before we could get them new homes.
<<Smart>>
Sad story turns good for most of the fish including two very young Percula
clowns, a Juv. Emperor Angel, and a small adult Majestic Angel. They seem happy
and healthy now. Unfortunately the fish in the worst shape was the Purple Tang
which is still not eating after two weeks! All of the fish are in the same
Q-tank, but the
poor Tang just seems to tread water and isn't doing much else. We have tried
all kinds of different food - various flake, frozen, live, Nori (soaked in
garlic, or Selcon) but nothing seems to work.
<<Mmm, if this fish doesn't recover/feed it won't be due to your lack of
trying>>
At first he was nearly completely faded and just leaned against the side of the
tank barely breathing. Now, his color has improved a great deal and he looks
pretty good. But he’s not active at all. We really don't want him to die, but
know if he doesn't eat soon, he will. (We’re dropping the temp in the Q-tank
from the usual 80F to 78F to slow down his metabolism). Is there anything you
can recommend to get him to eat?
<<I think you've done/are doing all you can...is up to the tang at this
point. Keep offering food daily, optimize water conditions...time will tell>>>>
This story leads me to my next and final issue for today:
We did not plan on adding any more fish after the Blue Throat Triggers, but we
have grown attached to these fish and have reconsidered finding them new homes.
<<I see>>
Our friend will put the Majestic and the Purple Tang in their reef, if he makes
it, but we’re considering keeping and putting the Percs and the Emperor Angel in
our main display tank. We have no idea what is considered too many fish in a
reef aquarium.
<<Highly variable...many factors to consider (system size/filtration, adult fish
size, species, environmental considerations/constraints, etc.)
It seems there are so many factors that can make a difference, so we are hoping
you can tell us if we are about to go over our capacity in the 7 foot long 260
gal tank:
<<Mmm...I'll give it a go...>>
The current inhabitants are:
Pair of Blue-throat Triggers (Male is approx. 7” and female is 6”)
1 Naso Tang (about 4.5”)
1 Yellow Tang (4”)
1 Blue Hippo Tang (4”)
1 Kole Tang (3.5”)
1 Coral Beauty (3”)
2 Firefish (2” each)
2 Purple Firefish (2.5”)
1 Mandarin (2.5)…but really fat!
2 Tomato Clowns (2.5 and 2”) [moving them to a breeder tank soon]
And:
3 Cleaner shrimp
2 Fire shrimp
Lots of hermits
Emerald crab
Various Corals
3 clams
All fish seem to get along except the Tomato clowns which are really
territorial.
<<Indeed...only fish I've ever had "draw blood" was a clown fish>>
We are planning to move them to a 29 gallon breeder tank with live rock and sand
and the anemone they host in.
<<Excellent>>
They have been laying eggs regularly and with any luck we can try raising the
fry.
<<I'd like to recommend you get a copy of the book by Joyce Wilkerson re
(http://www.fishlore.com/clownfishesbook-wilkerson.htm)>>
The main display reef has about 250 pounds of live rock, 40 gallon sump with LR
- ASM G3 skimmer - Aqua 25W UV - 3x250W DE Metal Halide/2x80W T5 - CPR Aquafuge
– Kalk Reactor - and we are about to add another 20L refugium to the system.
<<...? 20 liters or 20 gallons?>>
Do we have enough room to add the Emperor (knowing the zoos could be at
risk). Would this put us over the capacity?
<<The Naso and Hippo tangs will grow to be big, beefy fish...and the Naso may
even outgrow this system in time. But what you propose could work for a while>>
Would the Emperor bother my other fish?
<<Hmm, coming in last like it is...likely all will be fine>>
Thanks as always for your advice.
<<As always...happy to assist>>

Sargassum Trigger Fish - 07/18/2006
Hi guys/girls
<<Hi.>>
Quick question for you if I may :)
<<Go for it.>>
I have a Sargassum Trigger Fish.
<<Cool.>>
I have had him for a few months now. Slowly over this time he has
become progressively skinnier. Not really skinny, he eats a huge amount,
but just does not put on weight. I am just thinking he may have worms.
<<An internal parasite of some kind is likely.>>
What would be the best thing to worm him with?
<<I use Levamisole, a commonly available pig de-wormer.>>
We don't have a huge range of meds over here either, can you just use
cat wormer?
<<I’m not familiar with cat meds.>>
How much? How do you get it into them?
Soak some freeze dried krill in a solution of the Levamisole and tank
water. Do this for a few days.>>
Thought of mixing with food, but he tends to only eat whole things like
mussel, white bait etc.
<<See above.>>
Any ideas??
There is a photo of him (attached) when I first got him.
Thanks again
Tim
<<Glad to help. Lisa.>> |

Blue cheeked Trigger Fish in a Reef Tank? 6/5/06
Hello Crew,
<<Hello Bob>>
I'd just like to get your opinion of Blue Cheeked Trigger fish, (Xanthichthys
auromarginatus ), in reef tanks.
<<Absolutely worthwhile...if you have the space>>
I have heard much recently of the suitability of these fish to reef set ups due
to their planktonic diet, but they are trigger fish after all and those shrimps
look so tasty!
<<Ha!...indeed. There's always the possibility of trouble, but I've kept this
species in my reef for more than a year now without incident (I have shrimp and
snails but no hermits), and would heartily recommend you give them a try. I
think the biggest danger would be if you tried to introduce more shrimp after
the trigger is in the tank...would have to be introduced very carefully, not
just "dropped" in to the tank>>
My set up is 340 litre.
<<Mmm, marginal...should be "OK" for a time, but would like to see it in a
larger system for the long term>>
Stock includes leather and mushroom corals. 1 cleaner shrimp (Lysmata
amboinensis). Red- and blue-legged hermits. Turbo snails.
Fish list;
2 x Amphiprion ocellaris
1 x Ecsenius midas
2 x Pomacentrus alleni
1 x Neocirrhites armatus
1 x Centropyge bicolor
1 x Pseudocheilinus hexataenia
1 x Gramma loreto
1 x Ctenochaetus strigosus
Thank you for your time and expertise!

Re: Blue Throat Triggers in a Reef? - 07/18/06
Hi again you guys!
<<Hello Pam!>>
So, I took your advice (Eric) and I purchased two Blue Throat Triggers (BTT's)
directly from Hawaii a few weeks ago.
<<Ahh, Excellent!>>
They arrived a lot larger than we would have hoped, but they are beautiful
(especially him, but don't tell her!).
<<Indeed...wonderful fish>>
They looked very healthy but apparently came to me very stressed.
<<Hmm...possibly handled poorly>>
We weren't sure they were going to make it through the acclimation process (the
male was particularly stressed, bobbing head down in the tank and floating
almost completely upside down, it wasn't pretty).
<<Yikes!>>
Thankfully they did survive and once we got them eating a whole week later, they
seem great!
<<Yay!>>
It was very difficult to get them to eat. We tried everything from a homemade
fish food recipe all our other fish love, to live Brine shrimp, frozen Mysis,
krill, squid, and the list goes on.
<<I'm surprised by this, I must say>>
We tried to feed them for a full week to no avail......finally a fellow hobbyist
(from Wamus) told us about this frozen freshwater Mysis from Canada.
<<Yes, PE Mysis...an excellent food>>
He brought some over that night and we couldn't believe it...they inhaled the
Mysis!
<<Very good>>
I tried two other brands they did not touch before that!
<<Try them now...>>
Needless to say, I can't seem to feed them often enough-they love this high
protein stuff!
<<Be careful...several "small" feedings per day. Also, wouldn't hurt to soak
these in Selcon (or similar) a couple times a week>>
It is made by Piscine Energetic (FYI). For the past three weeks these BT are
feeding well, and looking terrific (until yesterday).
<<Ruht-Roh>>
We were planning on putting them in the main population since we just did our
water change in the main tank and my Q-tank is small for them. We noticed some
spots on the fins (especially on the male). We have been doing very regular
water changes in the Q (a few times a week) using water from the main tank and
keeping a very close eye on pH and ammonia. No issues. We did lose power a few
times about a week ago, but they had a battery air stone in there the whole time
(maybe it was stressful, but they seemed fine and the temp didn't change. They
are acting normal and look healthy so I don't know what to do about this (action
or ignore).
I don't think this is Ick because it doesn't look like salt and they aren't
scratching against the live rocks or anything. Luckily I am not a disease or
parasite expert since that has not been a problem in my tank and I have a UV
filter on the main tank. This looks like faded white spots on one of the tips
(not near the gills) of the male's fins and her lower fin (under her belly). I
am afraid to treat what I don't know and I am also afraid to do a freshwater dip
or anything that could stress these fish we have worked so hard to keep
acclimated and stress free. Does this sound like something that will treat
itself? Should I be worried? Do you know what this is?
<<Is smart of you not to panic/treat until you have confirmed the need to do
so. These spots are normal/natural markings...nothing to worry about. At first
glance they do appear very much like parasites, but careful observation will
reveal they are indeed markings on the fins>>
I have put some Kent Garlic Xtreme in the Mysis when I feed the past two
times-any other ideas?
<<I don't think you need be concerned...you can continue occasionally with the
garlic additive if you wish, it may serve as a preventive measure towards
internal parasites. You might also try it with the other foods as an
enticement>>
Long story short (I know, too late).....I am so happy you helped convince me to
get them.
<<It pleases me greatly to hear this>>
I can't wait to see them happy and swimming in the main tank. It was difficult
to get them acclimated and they have had some stress, but all in all seem to be
very happy and don't even stress during water changes anymore!
<<They will much appreciate a cave/crevice in which to hide/sleep...though they
probably won't inhabit the same one>>
It's been three weeks and I would like to take them out of the QT this week but
need to know if these barely visible spots are dangerous or if they will harm
my other fish. And what I should do if anything. I can't send a picture-it
doesn't show up.
<<No worries my friend. I believe all will be/is fine>>
Sorry to only write when I have a problem....but you always seem to save the
day.
<<Hee! High praise indeed!>>
Thanks!
Pam
<<Very welcome, do keep me posted on the pairs' progress. Regards, Eric
Russell>>
Blue Throat Triggers in a Reef? III - 07/18/06
Thanks again Eric-my hero!
<<I'm blushing, or maybe just beaming! <grin>... You're very welcome>>
I will keep an eye on them but feel much better now! I will try other
foods again with the garlic as you recommended.
<<Ah yes, and the Selcon/a vitamin product too>>
Thanks for the very quick reply and taking the time. You guys really
are a terrific resource and I appreciate that.
<<The guys and gals here are pleased to do what we can>>
Have a great day,
Pam
<<And you my friend. EricR>> |
