Help with my Rabbit Fish!
8/29/08
Sorry about the picture, but he is either in the rocks or under
the overflow. And of course the batteries are almost dead and the kids
have used all the spare batteries for who knows what.
<Have tried "spiffing up">
Any way, my rabbit stopped eating last weekend and was pretty much hid
all day long. I left for a 4 day business trip thinking he would be gone
by now but he is still around but looks like 2 face from batman now.
Half real dark and the other normal. He only picks at any food in the
tank.
I would appreciate any help here.

Siganus doliatus with a tick?
8/10/08
Good morning crew!
A "tick" is the best way to describe this strange behavior of our Scribbled
rabbitfish. We have had him for a week and was introduced directly into the
display. Bob F in a post on WWM said this was a good idea with this fish specie
as did Mark Martin from Blue Zoo (where we got him).
<Still my stance>
Anyway what this fish does when he comes out of the rock work is flick his
dorsal and pelvic fins for a split second at roughly one second intervals.
At first I thought this was some sort of threat to other fish coming too close,
but he does it regardless of where the other fish are in relation to him. Also I
have seen him hold those fins erect when other fish come too close and this is
not the same behavior. To further complicate the diagnosis he doesn't always do
it and sprints for the rock work if you try to get a closer look.
<Not atypical behavior>
I have manage to observe him up close by using a mirror (he didn't notice me)
and his gill rate seems unlabored and no quicker than my other fish. No apparent
spots or abrasions. Should I worry or name him "Goofy", lol?
Thanks
Ed
<And I'll be "Sleepy"... I do think this fish will be fine in time. Some
specimens, not just of Siganids, have a hard time, adjusting to small, captive
worlds. Bob Fenner>
Rabbitfish - Why do some have
that cloudy green eye? 1/14/08
I've been searching for some time for an answer, and can't find it anywhere.
I finally had to break down and bother those who are never stumped. Thank you
for being that source.
<Welcome>
I used to have a Foxface (S. unimaculatus) that had a metallic green, cloudy
eye. Something like a puffer or anthias. I would like another, and have asked my
LFS to keep an eye out for one (no pun intended). We're in southern California,
so he visits all the wholesalers personally, every week. He hasn't seen one
Foxface with the cloudy eye in the several hundred Foxfaces he's seen while
there.
Do we know why some have that feature? Is it regional? A part of maturation?
Random genetics?
As always, your help is appreciated more than you know.

Rabbitfish question, handling
12/15/2007
Hello.
I've got a one-spot Foxface Rabbitfish and we've had it for some time now. It's
doing well and growing like crazy.
We bought him in town and nobody told me that the spines could be dangerous.
<Oh yes>
Needless to say, we moved him between 3 tanks now and didn't know. I held him in
my hand at one point and even helped him get his gills going in the new tank
when the smaller tank he had been raised in crashed. (We had numerous newbie
fish disasters throughout the year, but everything is a+ stable now).
I am concerned after finding out that they are venomous, quite by accident,
because nobody took the time to tell us, knowing we were newbies.
I've searched the site thoroughly and read the Rabbitfish FAQs, and I see that
it mentions that they have a painful sting and are venomous. It does not,
however, tell you how venomous they are (from what I saw, but I may have missed
it somewhere) or if they are actually fatal, such as the lionfish can be.
<Somewhat less than Pteroines... more than bees... Can be dangerous to folks who
have aversion to proteinaceous stings>
I am concerned, needless to say, because he's grown to about six inches long and
he's quite the boss of the big tank, with the exception of a few of our tangs,
who rule the roost.
Thank you
<I too have hand-handled many Siganids... one just needs to be careful to keep
their hands away from the spiny (anterior) portions of their dorsal and anal
fins... Bob Fenner>
Odd fish behavior... Frantic Rabbitfish
– 09/29/07
I have a 75 gallon reef tank with a 20 gallon sump/refugium which has been
going for about a year now. It is stocked with a yellow tang, a Foxface
Rabbitfish,
<Which species?>
a ocellaris clownfish, a four stripe damsel, and a dwarf lionfish. All of these
fish have been in the tank for several months with the exception of the Foxface
who was added about 4 weeks ago.
Yesterday, I noticed that their behavior seemed odd, they were swimming around
almost frantically and acting distressed.
<... likely reacting to its own reflection... which you may well not be able to
see through the outside.>
The color was looking mildly faded on the Foxface but not too bad. Since all the
invertebrates were doing well I doubted a water quality issue, but went ahead
and ran the tests anyway, and came up with no detectable ammonia, nitrite, or
nitrate. There have been no changes to the tank in months with the
exception of adding the Foxface. Today the behavior is the same: swimming
frantically back and forth, not at the surface and not gasping, just behaving
frantically. All the fish eat and the coral do not seem to be distressed. Any
thoughts on what could be causing this behavior and should I worry about it?
<Mostly the reflection... but this is a small volume for a Siganid...>
The tank is open-topped, is it possible that something foreign got in the water
and is causing this effect on the fish without effecting the coral? Thank you
very much and I look forward to reading your response.
<Try covering one end of the tank exterior with dark paper... Bob Fenner>
Re: odd fish behavior 9/30/07
Thanks for the response! In reply, I have had the back of the tank covered
with a black fabric since the tank was started up,
<Mmm, I would still try covering a side... internal reflections are bounced off
of these>
and there are many places for the fish to hide in the tank to feel secure.
<Well... actually Siganids range over areas of tens of square metres...>
My concern with their frantic behavior is that it is a dramatic change from
their normal behavior. The tank walls are regularly cleaned so the
reflectiveness should be relatively constant, so why the sudden change in
behavior?
<The sun transiting on the azimuth... likely>
To further illustrate, the fish previously would see me approach and swim up the
front of the tank and eat out of my hand. Now they swim away and hide and when
watched from across the room they will continue to swim in fast bursts
frantically in and out of the rocks.
<Mmm, does seem bizarre... Has something else frightened them I wonder? Like the
lights being suddenly turned on when it is very dark outside>
The Foxface is also frequently losing color and is rarely as vibrant as he
should be. I would assume that if the dwarf lionfish had stung any of them they
would not survive.
<Actually... this may well "be it">
When the Foxface was first introduced the yellow tang had initially established
dominance over him, is it possible that now that the Foxface is accustomed to
his environment he is making an attempt at establishing dominance over the tang?
<Also a very real possibility>
The tang and the Foxface seem more frantic than the clownfish and the damsel, so
could that be a possible cause?
<Yes>
Mainly what I want to know is should I do something?
<Yes... if it were me, and this behavior persisted, I would move, trade out one
of the Acanthuroids>
As of now I'm monitoring the situation but have done nothing to correct it and
this is the third day with no change. Any recommendations? Thanks again very
much.
<A bigger tank or removing the tang or rabbit. Bob Fenner>
Foxface- losing color 12/14/06
I recently added a Foxface to my aquarium after 3 weeks of quarantine. He
is my first fish in an aquarium that finished cycling about a month ago. While
in quarantine, his colors remained nice and clear, bright yellow on his body.
After adding him to the display tank, his colors remained vivid for the first
few days, but he has since started to look very pale whenever the lights come on
in the aquarium.
<Mmm, natural to an extent... like many reef fishes... have a "night-time"
coloration, pattern... Thought to be of camouflage value.>
Where his body was once yellow, he is now showing a good bit of white.
<Oh! The change/ing is persistent?>
When the aquarium is lit by only a light being on inside the room, his colors
appears to be normal. His color changes, and sometimes he looks perfectly
normal, but this can change very quickly- as I know that foxfaces can do. But
he has never before displayed this pale coloration on his body during the
daytime, which makes me think something is possibly wrong.
<Yes... perhaps something, someone bothering this fish...>
He is eating very well, I have some algae growing in the tank and he eats this
constantly.
<A good sign>
One reason I purchased this fish was for their algae consumption, I do have some
algae growth on my live rock- not sure if it is filamentous diatom or green
hair, it is brown in color and very wispy fine. I also feed him some fish
pellets as well as frozen packaged food that has small compartments of different
meals, so he can eat something different every day. So far, I haven't found
anything he won't eat. Could something be missing from his diet that is causing
his color change?
<Mmm, a possibility, yes>
Could the algae growth be consuming too much oxygen from the tank?
<Interesting speculation... doubtful though, if this tank is "large enough" (at
least 75 gallons), circulated, filtered....>
All his other looks and behavior appear to be normal, so I'm really at a loss
for his not having what was once was his vivid color patterning. My water
parameters, (last checked about 3 days ago) were 0 ammonia, 0 nitrites and the
lowest possible number for nitrates on my test kit. I plan to recheck all of
these numbers again tonight. Can you provide any information that might help me
out here, I really like this fish and want to provide him with the best care
possible.
<Need to know the other tankmates present, how much LR you have... can this fish
get "away", out of the light?>
I want to mention again, this white coloration is not always present, but
seems to be his preferred coloration more often as the days go by. Thanks for
all your help and wisdom.
Kevin
<And this fish may still be just "settling in". Bob Fenner>
Re: Foxface- losing color 12/15/06
Bob- thanks for your input concerning the color changes in my Foxface. To
answer your question concerning the other tanks inhabitants, this is the first
fish I have added. Also, you were saying the algae growth shouldn't be a
problem if the tank is large enough, this is a 215G aquarium. Since writing to
you concerning my Foxface, I have since established a better pattern to his
turning this white color. It seems as though it is not the lights coming on
that causes him to lose his pigmentation, but instead it is my presence!
<Ahhh!>
When I approach the aquarium, which is usually about when the lights come on
since this is when I feed him in the morning, he turns almost a pure white with
no trace of yellow hardly left, even his dark spot fades to a dull gray. He
does not seem stressed or scared by me, in fact quite the opposite, he now
approaches the glass when I appear where as he used to hide (but stayed yellow)
. So it this his way of showing excitement at getting ready to be fed?
<Possibly both, neither... "just" stress period>
I can't imagine any other thing. As soon as I leave the tank and stand some
distance away he turns back to his yellow. This is kind of still troubling to
me, as I have this very pretty fish who is going to turn into Casper the
friendly fish every time I want to see him. At night he goes into his usual
camouflage brown pattern, but this look is during the daytime hours and he looks
albino! At least if he is not going to be the prettiest Foxface for someone to
view, he will for sure be quite a conversation piece for my aquarium! Have you
ever heard of such? Thanks so much for your time and thoughts.
Kevin
<Mmm, very likely in time this fish will "stay" about the same colour when folks
approach the tank... a bit of B.F. Skinner conditioning... Bob Fenner>
Foxface Envenomation (Ouch!) - 10/25/06
Two weeks ago, I was stung by 3 of my Foxface Lo's dorsal fins on the
inside of my wrist, for two hours the pain was quite intense.
<<Indeed...yikes!>>
It was suggested that I soak the wrist in as hot a water as I could
handle for at least 1-2 hours -which I did.
<<Yes, it is believed the high temperature breaks down the proteins
comprising the venom>>
It seemed to have solved the problem the three marks almost disappeared
in a week.
<<Ah good>>
Then this week the marks began to turn red and turned into 3 small
reddish blisterish looking marks and the skin area around them is
slightly red around now as well.
<<Mmm...>>
I am not sure if this is the type of questions you can answer but here
it is. My question too you, is this - Have you heard or read of any
unusual side effects from the Foxface lo venom?
<<Have heard the wounds can be slow to heal, with secondary infection a
reality. But as with bee stings/other envenomations, some individuals
will react more severely or less severely to the toxin than the
"average" person>>
Could this just be part of the process of the venom leaving the body?
<<I think this is a "secondary infection">>
I would appreciate any input you may have.
Thank you,
Rhonda McAskill
<<Were this I, I would have these wounds checked/treated by a
doctor. Regards, Eric Russell>>
Scared Foxface 10/26/06
Howdy Crew,
<Robert>
As a first time e-mailer, I would like to thank you so very much for your
informative website. It has saved my Fish, Tank and Wallet many times over.
<Glad to read>
My question today is about my Foxface that I have had for about a month. My
lighting setup is a dual 4ft fluor (one white and one blue) and a blue
moonlight. These lights switch at the end of the day cycle as
follows; moonlight on, white fluor off, blue fluor off. When my White fluor
switches off my Foxface goes crazy, he darts around for a few seconds then
hides in the rock.
<Mmmm, yes>
He loses all of his colour (Due to the fright) and sits
there startled with his mouth wide open. My guess is this is not very good
for him. Do you have any ideas how I can prevent this?
<A larger system, more cover to hide in... a dimmer mechanism to phase light
in/out more gradually>
Is there something
out there that I can use to dim these lights slowly? Or will the Foxface
just grow out of it?
<Do check with Champion Lighting, MarineDepot (.coms)... re such gear...
Siganids need much larger quarters... Bob Fenner>
Thank you in advance,
Regards,
Robert

Fish anesthetization in the aquarium 9/9/06
Dear Crew,
I have done a fair amount of research on the anesthetization of
fish.
I give anesthesia (human) for a living so I understand the
chemistry and pharmacology of the agents available.
<Ah, good>
I need to get a Magnificent Foxface Rabbitfish out of my 300 g. saltwater aquarium. I, and my wife, and my son (who works for the LFS) have tried many times to capture this fish, I have tried to use the bottle trap a number of times... suffice to say that
because of the design of the tank and the layout of the live rock (many, many, many hiding places) I have decided to begin researching anesthetizing, or at least sedating the fish just enough so that I can net it, and get it back to the LFS.
They pointed me to MS-222, and I have done further research into tertiary amyl alcohol and other agents also including Carbon
Dioxide.
<Mmm, I would use none of these in an established aquarium. And have
used all of these...>
All the info I have found so far describes the use of the agent
with the fish already in an isolated container. Obviously if I had the fish in an isolated container, I wouldn't have a problem, so what
I would like is your view of using some type of agent in the
aquarium itself. I realize that this will affect the other fish (One 10"
Naso Tang, one 5" Banggai Cardinal, one 3" Lawnmower Blenny, one 3"
Blue Spotted Jawfish, one 2" Hector's Goby), the 5 serpent stars and
about 30 corals to some degree or another.
Any thoughts, or suggestions you may have would be greatly
appreciated.
Thanks in advance,
Dave Harvey
<If it were me/mine, I'd first try a fashioned "squeeze net" to push
the one fish down toward one end (two inert poles and some
reasonable size mesh netting)... and two hand nets once isolated in
a smaller, more manageable volume... or "bite the proverbial bullet"
and drain the tank down... into containers it can be re-pumped back
into the main tank... Bob Fenner>
Jumping Foxface 9/9/06
Hi WWM Crew,
<Diana>
I have a quick and maybe silly question.......
My Foxface (Siganus vulpinus) has jumped out of the main tank and
into the overflow compartment.
Do you have any hints on how to get him out fast and unharmed?
Thanks for your input, Diana
<Not with your hands! Siganids can/do give nasty cuts and are
venomous... Use a soft net of size to fish out and place back in the
main tank. Bob Fenner>
Foxface Rabbitfish seems darker than at pet shop... 9/9/06
Hi, I have a Foxface Rabbitfish in a 50 gallon tank
<This siganid (and most all other species in the family) needs more
room than this>
for about a month
now and for some reason his yellow seemed a lot brighter at the LFS.
<Good observation... turn dark when "upset"... something wrong>
Could it be because of my light set up? (2 96w 1 12k white and the
other
12k actinic) He will only get darker when scared but never any
brighter.
<More likely the size of this world... perhaps other tankmates...
but light could be a factor>
My water levels are just right and he's only about an inch and a
half.
<Wow, small>
He should be fine until I upgrade for a 100 gallon in a few months,
no?
<I hope so. Bob Fenner>

Foxface Slime Coat Slipping Off - 03/27/06
Hi,
<<Hello>>
Lee here, first time writing long time reader.
<<Welcome Lee>>
I recently purchased a Foxface that was quarantined about a week with no
problems.
<<Mmm, best to leave a minimum of three weeks when placing livestock in
quarantine.>>
After adding to main tank, a 150 gallon, within day or so developed few black
dots. I then gave heavy doses of garlic and these all cleared up. Now about
every two days he develops a white film that sloughs off by itself.
<<Normal for these fish.>>
What is this?
<<A mucus coating...Siganids (in particular the Foxfaces) have a very heavy
slime coat which they seem to be able to "shed" at will...nothing to worry
about. My Siganus uspi sheds its slime coating daily (usually when excited as
around feeding time). The slime coat is even consumed by other fish in the tank
on occasion.>>
He eats great and it doesn't seem affect him.
<<Nope>>
All tank levels are at 0 with salinity at 17 and temp at 78 degrees.
<<I prefer to see salinity kept at normal seawater levels (1.025/026)...for all
saltwater tanks.>>
I have a 75 reef tank that is about 4 years old and never have seen anything
like this. Any help is appreciated. Thanks!!
<<Regards, EricR>>
Fading Foxface
Hey Bob,
I have a question regarding my Foxface...I have had him in my 65 gallon
fish-only + live rock tank for approximately 2 months, and am concerned
about his loss of color. He was vibrant yellow when I brought him home,
changed all kinds of mottled colors and then faded over the course of the
first few days as expected, but his "true colors" never came
back.
He seems healthy...eating well and all that stuff, with plenty of
greens (marine algae from Ocean Nutrition). I typically break off a 2"
x 2" square for him to pick at during the day, and feed some
combination of Formula 1, Formula A, brine shrimp, and Vibra-Gro in the
evening (not all on the same day!). I supplement with Selcon a few times a
week too.
The water parameters are OK too:
Ammonia: 0
Nitrite: 0
Nitrate: 5 ppm
pH: 8.3
Temp.: 80
Do I need to take his fading as a sign of poor care? Is there anything
else I should do? Thanks for your help and for keeping this insightful
column!
< Chris, thanks for the well written note. You have done about all I would do
with your Rabbitfish (the Foxfaces are part of the family Siganidae), feeding
greens, having live rock about, adding vitamins, providing clean water... About
the only two things that come to mind are bullying (by other livestock) and the
chance that your system is too brightly lit. Both might be alleviated by making
sure you have enough hiding spaces for the Foxface to get out of the light and
hide in a large enough "cave". Can you make one out of your
décor/live rock? Bob Fenner>
What's Up Doc? Problems with a Rabbit Fish
<Hello, JasonC here filling in for Bob while he's away.>
I have had a magnificent Rabbitfish for 2.5 months now. Recently I have noticed
it gulps air and blows bubbles out of its gills. I suspected this was lack of
oxygen so I added some air pumps to the tank. I already used the following for
filtration/aeration. Turboflotor skimmer, numerous powerheads, drain/return pump
sump system.
<should have had plenty of aeration from the skimmer.>
I have three large tangs in the same tank ( yellow, Naso, regal) as well as a
medium sized Blueface angel. None of these gulp air. The rabbitfish's gills also
only move as much as the tangs. Finally the Rabbitfish shows no other signs of
stress. It has intense coloration, clear eyes, mark less skin, and a very varied
and healthy appetite. Any help would be appreciated.
<hard to tell, from your description everything else is normal. How big is
your tank? You might want to go through the Rabbitfish FAQ: http://www.wetwebmedia.com/siganidf.htm

Thanks, Everett
<You are welcome. Cheers, J -- >
Re: Problems with a Rabbit Fish
<Hello, JasonC here... >
Hi my tank is 240 gallons with a 40 gallon sump. I have stuck air hoses in all
of the pumps but it still sucks air.
<as I said earlier, I don't think that you water is oxygen-poor, so adding
more air hoses won't help.>
It still looks and acts normal.
<then perhaps this is just a behavior or something the fish enjoys doing. As
long as it's not hurting itself or in deteriorating health, I wouldn't worry
about it. Some fish do this... my puffer does constantly around food time -
gulps air, spits water.>
Thanks for the help, Everett

Rabbit fish questions
scenario= 125 gallon tank, ph 8.2, ammonia 0ppm, nitrite 0ppm, nitrate 5ppm,
tank has been setup and running for about two months. 2 bio-wheel 400 filters
and Protein skimmer. Current fish include 5 black mollies (starter fish) 1 blue
velvet damsel and a fox-face rabbit. Two weeks ago I made the mistake of getting
1 clarkii clown, and 1 bi-color angel on a Sunday and then 1 yellow tang and my
fox face on Monday. This must of caused an ammonia spike as I lost all my new
fish except my fox-face rabbit. The rabbit fish eats good (flakes), and is
active. I have normal aquarium lighting set up on a timer 11 hours on, 13 off
1 Sometimes the fox face will go to the top of the tank, behind the filter
intake, and spike his fins and turn almost all black. He will stay like this for
2-5 minutes. I can't see that any of the fish in the tank are aggravating him.
He seems to do this most often when I near the tank. Is he stressed?
<During these moments, yes>
2 His colors have faded since I brought him home. His yellow isn't as bright as
it used to be. I have tried to feed lettuce but he won't eat it. Is there a
proper way to feed lettuce?
<Don't feed lettuce, or other terrestrial greens... Please read through the
marine foods/feeding/nutrition and Rabbitfish/Siganid materials stored on
WetWebMedia.com>
I have tried hanging it near the surface and also sinking it to the bottom with
an alligator clip. Any suggestions? Thanks for your time, Chad Dugger
<Study my friend. Bob Fenner>
Foxface
I have had a Foxface in a 20 gallon tank for almost a year
now. He has always been pretty shy. He has dark tiny dots
on his white stripe on his snout. I've looked at some pictures on the
web and noticed they do not have these dots. He's acting normal but I
just wanted to make sure nothing is wrong. Are these dots normal?
<Are they symmetrical... on both sides of the head? Likely not a sign of any
infectious or parasitic disease>
P.S. I know he's in too small of a tank and I'm about to move him to a 120 in a
few weeks.
<Thank goodness, providence. You will likely see these "environmental
stress markings" go away with the move. Bob Fenner>
Fox Face Color
Crew,
I am curious about the coloration of my fox face. I was looking through the
pictures on the WetWebFotos site and noticed that my fox face has a
similarity to a Siganus magnificus in that it has a brownish blackish streak
across the top of his body. This is whether he is stress or not. I know my fish
must be a vulpinus because it has the second black patch by his
"throat" in addition the one across his eyes. My LFS said that this
happens to his fish when the tank it is in is colored on the back. Is this
camouflaging or a dietary thing? He gets fed Nori soaked in vitamins as well as
Ocean Nutrition's #2 food for herbivores etc. Want to keep him healthy.
Thanks, David
<Well, David, in the absence of other outward signs of illness, injury, etc.,
Id be inclined to agree with the dealer. These fish, and many others, can and
will change coloration (both intensity, and to a lesser extent, patterns) in
response to various environmental factors (stress, chemistry parameters,
lighting, background, etc.). Another possibility is that your fish might even be
a geographic or individual variant of one of the species. If the fish is eating
and behaving normally, I would think that there is little cause for concern.
Just to reassure yourself, you may want to run tests on basic water parameters (i.e.;
pH, Alk, Nitrite Ammonia, Nitrate). Keep making regular water changes, keeping
stable temperatures, and feeding a good diet, as you appear to be doing. Keep
observing him daily, and be prepared to act if you need to correct any of these
parameters. Good luck! Scott F.>

Shy (Not Sly!) Fox...Foxface question
Hello, { another '17' on the way ;-) }
<Hello! Scott F. with you today!>
I have had a Foxface for 2 weeks and he was great till yesterday... Every time yellow,
active and with smile on his 'foxy' face... Since tomorrow he is sitting behind
the rocks and from time to time (rarely) showing his nose. I don't know what's
wrong... His stings are rather hidden {but when picking pellets, they are
opened}, but he looks like 'zebra' {black & white}... Is stress cause that
behaviour or my eyelash blenny which is swimming like crazy {REALLY active
fish}??? It looks like foxy is quite scared but I don't know why... Is it
normal that Foxface from time to time has that kind of behavior???
Thanks
<Actually, yes.. In my experience and observations of others, these fishes
are much like tangs...Some individuals are very, very "outgoing" and
social, and others are amazingly shy. And, of course, it's certainly not an
unusual occurrence for these guys to go through periods of time where they are
shy and inhibited. I'd keep a close eye on the blenny to see if it is, indeed
irritating the Foxface. If the fish is otherwise healthy, then I will venture to

Freaky Foxface- Or Normal Behavior?
Hello -
<Hi there! Scott F. with you today>
I read the existing comments posted about various Foxface Rabbitfish issues, and
have these questions:
Is there something wrong with my Foxface? He stresses at least daily,
changing color, hiding, being very still?
<Very typical for a Foxface, in my experience>
Is my tank - 55 gal, too small for Foxface? Fish is about
4"-5".
<I think that this tank is too small for long-term maintenance of this
fish>
Other facts: 55 gallon tank, with 1 small Green Chromis and 1 Orange-Spotted
Goby, several snails, hermit crabs, 55 lb live rock, hang on bio filter, Remora
skimmer, power head, compact fluorescent light, 1 sand sifting star fish, 1
Arrow Crab, 1 Bubble Anemone (clown died). My water levels, salt, ammonia, ph,
etc are all good, checked weekly. Foxface's appetite is very good, eating varied pellets,
flakes and dried seaweed. I have had him for 4 or 5 weeks. The
tank is about 2-1/2 months old.
Your suggestions will be appreciated. Thanks,
Jeanette
<Well, Jeanette, your tank sounds fine. These fishes tend to reach a large
size, and, like tangs, require large amounts of space to be truly comfortable
for the long run. So, if a larger tank is in the future, things should be fine.
Regards, Scott F>
Magnificent Foxface
Hi Guys,
<Hi, MikeD here>
I have a question regarding my Magnificent Foxface
(Siganus Magnifica). He is such a beautiful fish and I
got him for $55 from my LFS. (partly from a discount
he gave me 'cause we're friends, partly from no one
wanting him for some reason) He has been in my 120 for
about 3 days.<Can I ask how large this fish is, as sometimes it has a
significant bearing.> At the store, he was active and not shy
at all, but when I put him in the tank, he hid behind
the rock all night.<Normal> I suspected everything was fine
and that he was just scared. The next day he came out
a little and today he was out to eat. He's doing fine
but I was wondering if he would eventually come out
and swim more once he gets used to the tank.<Probably, but that depends on
several things> Right now
he uses his spines to hold himself in place behind
various rocks. When my LFS took him out of his tank he
had to triple bag him because he kept poking the bags.<You ARE aware that these
fish have venomous spines about as potent as those of a Lionfish, correct?>
LOL, it was apparent he liked where he was. Also, I
was wondering why they change color. It seems like he
is trying to camouflage with the rock. He does it when
frightened. This is normal and isn't unhealthy right?<Foxfaces normally
camouflage themselves for two reasons, 1) out of fear or stress, and 2) at
night, with eh blotchy night-time sleeping pattern VERY normal>
He is a very beautiful fish and I consider myself
lucky to have him, as no one else seems to care about
any of the Foxfaces, even though they are reef-safe
and hardy. Why is that?<In my experience, Foxfaces tend to exhibit what I call
the "target fish syndrome" more than many other families, meaning that if they
are the largest fish in the tank they KNOW that would make them the most
obvious, thus preferred target for attack by a predator, in other words meaning
they are high on the intelligence scale. This behavior will often decrease if
kept with other fish of the same or larger size, EXCEPT for other Foxfaces! Some
Rabbitfish will tolerate others of their own kind or relatives, while the
Foxface end of the family (Lo, vulpinus, Fiji) tend to be aggressive toward the
rest and often need to be the ONLY member of the genus kept in a tank lest an
all out war erupt. As to reasons for the apparent lack of popularity, the venom,
of course, is often a deterrent, along with the larger size (up to 8" or 9"
which is considerable in a 120 gal. tank if it's a typical reef system). As to
his shyness in your tank, you didn't mention the size of the tank he was in and
with how many and what size tankmates, nor what else you have in your tank. If
he's the only fish in there, the shyness is likely to be long term, and if the
tank is in a high traffic area, even more so. There IS an upside to this as
well though....being more intelligent, if you're willing to make "friends" with
him, eventually he'll develop almost as much personality as some of the puffers
and triggers and become a truly "Magnificent" showpiece, but you'll literally
need to earn his trust. these guys, by the way, have an insatiable appetite for
veggies, even compared to other vegetarian species (I have a 7" Lo Foxface that
can devour a full half pound of Caulerpa in an hour or less, and no, I don't
know where he puts it either!**grin**) Mine is maintained in a 300 gal. FOWLR
tank with larger predators and large tangs and is ANYTHING but shy, with him
being a problem and harassing a Vlamingi tang that's 3" longer for several
months. I acquired him when small and he was house with several other Foxfaces
and Rabbitfish, but as he got larger they had to be removed to save their lives,
with his attacks constant and ongoing.>
Thanks, you guys are awesome,
Jake
Magnificent Foxface (continued)
Hello Again<Hi back! Mike D again>, In response to your first question, yes
I
am aware that the Foxfaces are a venomous group, but
your hands stay out of the tank, so I don't mind :). I
realize that his poking the bag was a defense to try
and "sting?" it so that he would be let free, I just
thought I'd mention it because my LFS said he's never
had to triple bag a fish before<LOL! I've had to triple bag MANY fish,
particularly those with sharp spines....it's REALLY impressive when you have to
triple bag a fish because it BITES through two or three thickness of bags!>, I
commented you must
have never had a Foxface before then<Wrong. I started out with 5 in a 125 gal.
tank and gradually had to remove them due to aggression among themselves.>. I
suspected the
very same thing of his camouflage patterns, as when I
approach he sticks his head out from a rock, turns
color with the rock, and doesn't move. very
intriguing, and I'm sure he'll warm up to me.<good luck. I commented on their
"biggest/Only fish syndrome" and suspect that in 6 months he'll be doing just
what he's doing now.> As for
their veggie consumption, I read about him in "Marine
Fishes" long before I got him and knew that he would
be needing a lot of this matter. I feed him quite a
bit of Spirulina (it says to feed them that in the
book) he eats well and I'm not worried about him
staying healthy.<they need a varied diet and JUST Spirulina won't suffice.
Caulerpa, romaine lettuce, spinach and FD algae sheets will help and these kids
eat a LOT of veggies, as well as a fair amount of protein based foods> I'm
shocked however to hear that you
say they can be aggressive, as they seem harmless to
me, but I guess that's an unfair statement when he's
the only fish in there<The aggression displayed by the Foxfaces is generally
aimed at their own kind and near relatives, although, as I found out the hard
way, MAY be directed at other fish that they consider competitors as well. As to
"seeming" harmless, drop a lettuce leaf in the tank....the mouth and teeth may
be small, but they are VERY effective, particularly when the attacks are
constant and non-stop. The Foxface I have was attacking a vlamingi tang a full
2" larger than it is (about 6"-7"). It's a 120 gallon tank, five
feet long with 180 pounds of LR.<I gave mine away to my neighbor after placing
it in my own 125 gal. tank as "punishment" top see if it would lessen the
aggression....I BOTH tanks, it stayed hidden in the LR and refused to come out
except to eat occasionally, even though there were several other smaller fish in
both> Anyways, now that
you say he can become aggressive if the biggest fish
in there, I am a little worried. He is 5-6 inches
long, and I was thinking of putting a medium sized
tang in there, (one of the Acanthurus members, don't
know yet) Would he too get along?<Quite possibly. In my 300 gal tank the
Foxface
was a terror towards the Vlamingi tang (genus Naso) and yet completely ignored
an Acanthurus tang that was placed in there at the same time> Rabbitfish and
tangs are "cousins" but not closely related enough too
fight to the death, I would think.<THIS is where the rub occurs...it's not
important what YOU think, but rather what your individual Foxface and Tang
think. Each fish is an individual with its own specific personality and the
books can only give a general suggested guideline on what MOST members of a
given species are likely to do. Fish, however, don't read the books and have no
problem embarrassing authors on a regular basis. Keep in mind that out of 10
fish, for example, 7-8 are likely to act as expected, but one will probably be
much more aggressive than the norm and yet another may be extremely submissive
and shy. It's been my experience that this applies to pretty much any animal
species that I've ever kept, and there have been many. I currently have a 300
gal tank, 2-125 gal tanks, a 100 and a 25 gal hex>
Let me know what you think,
Jake
P.S.- I apologize for being so long winded tonight.<Me too, only it's not just
tonight. No apology needed and good luck>
Magnificent Foxface
Mike,
<Hi again, I'm baaaaack>
Now I am a bit confused.<A soul mate!> Does the Foxface not like to
be the biggest in the tank usually no> or does it like to be because if
the vlamingi was bigger, wouldn't he feel less
threatened according to your biggest fish thing.
By the way, he has already started to trust me more.
(He loves his food and recognizes me as "The Food
Source")<You could be lucky and have gotten a more outgoing specimen. Like any
animal they come in timid, average and aggressive depending upon the individual
fish>
I want to get some of that "tang heaven" (both the
Gracilaria and the Ulva) for my tang when I get one. Do
you think that the Foxface will devour this stuff at
the same rate as tangs?<Nope....MUCH faster. These guys REALLY like their
veggies and you may have a tough time getting any to a tang.> Thanks for your
time.<NO problemo. Time I have plenty off!**grin**>
Jake
Scared Rabbit? (8/30/04)
Hi, <Hi. Steve Allen with you tonight.>
I have had a Fox face for about three years, he always eats very well, I noticed
yesterday that he was hiding behind coral and his face was very dark and had
dark areas on his body. <This is their typical night/fright
behavior/coloration.>
He is about 5" in length in a 110 gallon tank. Today his color is better but
still did not eat and is swimming at the top. any help would be appreciated.
Thanks Denis <Really tough to say. Have you added anything new? Done something
differently? Changed something? How are your water parameters? Do you have any
other fish in the tank that might suddenly have gotten aggressive? Any signs of
disease, such as scratching, rapid breathing, etc? These are some good starting
questions to ask yourself as you try to figure out what the problem might be.
Hope they help.>
Foxface
Is my fox face sick, he seams to eat well and swims ok, but scared and puts up his defense with his fins. At times his eyes
seem cloudy. My tank is a reef tank, We have him mixed with 1 yellow tang 2 clown fish 1 blenny scooter 8 gobies 1 cleaner wrasse, and our tank been up for about 5 months and all the other fish seam to be fine and I have them in a 90 gallon tank.
<Nora, I believe the fox face flares up due to the yellow tang that is present. Nothing to worry about. As for
occasional cloudy eyes, this could be diet. Fox faces do like algae. Have you tried feeding it the freeze dried algae? Also add some vitamins to all the fishes diet such as Selcon or similar. They will all benefit. Do you perform water changes on a regular basis? James (Salty Dog)>
The slime I thought came from the corals is from... the Foxface!?!
9/13/05
Hello All.
<Howdy>
Ali wrote me back on my feeding question the other day regarding this lovely
fish. What I had mentioned was that I thought from perhaps excess feeding
the corals were stressed as there was a milky white cloud or slime near them
and on the Foxface. Of course since the first I had seen of it was after I
saw the Foxface among the coral I attributed this to the Hammer corals. Now,
I see that this substance is coming from the Foxface.
<Yes... Rabbitfishes are quite slimy>
It seems to come
mainly from the dorsal fins top and bottom. And the clouds come as it swims
quickly through the tank. I still need to recheck the water parameters but
the values were: nitrites 0 nitrates, 10-15ppm, SG 1.023, pH 8.1-8.2
temperature 77F only 2 days ago.
The fish eats well, is very interactive and bright in color (unless sleeping
or spooked). Before I go ‘fresh water dipping it’ as I know these are
generally hardy but the spines can be an issue when handling, more so in
nets, I thought I would see if this something not abnormal and avoid
stressing the poor fish unnecessarily.
<I would not freshwater dip, net this fish here>
I checked the FAQs but came up empty
on the hits for Foxface and Slime…. What else should I have typed in?
Thank you,
James Zimmer
<Perhaps an issue we just haven't come up with yet. Cheers, Bob Fenner>
The Disappearing Rabbitfish? 10/18/05
Hi,
<Hi there! Scott F. here today!>
Been an avid reader of your site with much priceless information learned. I maintain a 125 FOWLR tank, moderately stocked, Naso & yellow Tang, Flame Angel, Maroon Clown, along with some Chromis and Damsels. Tank has been up for about 4 years, and most inhabitant are in that long. Latest additions are the maroon clown and Naso Tang. The Naso which is the largest in the
tank (5-6") still gets picked on and evidently does not know how to use his "scalpels".
<This will definitely change at some point!>
Anyway, about a week ago I purchased a 2-3 inch Foxface which was eating nicely and active at the dealer. After an acclimation and dip I put him in the display tank (I know..)
<Ok...you get spared the quarantine lecture this time... :) >
He went right to an upper corner and looked pretty stressed out, hung out there for a bit and then disappeared in or
behind the rock (lots of caves, nooks and crannies). Have not seen it for week now! Is this normal? Will it ever come back out? No one seemed to be bothering it although the tank is always "moving". Tank is well fed and plenty of grazing available (Due to be well fed I assume!)
Thanks,
Mordy E
<Well, Mordy, it's hard to say, really. It's certainly not uncommon for newly introduced fishes to hide for some period of time. However, fishes like Rabbitfishes like to be out in the open and swim actively, so I'd say that, categorically, they're less likely to hide for prolonged periods of time than, say- Wrasses, Dwarf Angles, etc.
Adding to this the fact that these fishes graze constantly on algae, and there is some cause for concern. I wouldn't give up just yet, but I would continue to keep a vigilant watch on your tank to see if he emerges. I would give it a few more days before I'd really start to think the worst. I suppose you could dismantle the rockwork in an attempt to locate the fish, but I'd be hesitant to do that, for fear of disturbing the other tank inhabitants.
Also, a spooked Rabbitfish can accidentally nail you with those venomous spines, so be very careful if you choose to go this route. My advice is to keep up the faith and wait it out a bit longer before concluding the fish's demise. Obviously, continue monitoring water conditions and be prepared to take corrective measures if the fish has expired and affected water quality. Keep those fingers crossed! Regards, Scott F.>
Foxface Rabbitfish Getting Dark Back 10/21/05
Hi Crew -
<Marc>
Have you ever seen or herd of a Foxface Rabbitfish's back getting dark?
<Yes>
The top half of his back on both side is getting darker, but the rest of him
is still yellow and vibrant. He seems healthy, eats fine, etc. It is
happening when the full lights are on, so it isn't his night colors (2x96
watt CF and 2x175W HQI). He has been in the tank about 2 weeks. Thoughts?
Picture attached.
<Pic didn't come through... likely "just" stress... if "both sided"... do you
have dark/er areas where this fish (and your other livestock likely) can "get
out of the light?" Bob Fenner>
Foxface 11/6/05
I've got a Foxface Rabbitfish that is having problems. He can't swim well,
and has been seen panting on the sand a few times.
<Good observations, bad behavior>
He tried to swim but can't do it well and refuses to eat (when he's ALWAYS my
biggest eater, although I don't overfeed him). Nitrates/Nitrites/Ammonia is
normal at 0 ppm. It's not overcrowded and there's nothing that I would think
bother him. The only fish that could is my blue tang and orange shouldered tang,
but both are half his size.
<... can still be harming this fish psychologically>
I also have a pair of banded coral shrimp, a lawnmower blenny, mandarin, a clown
and random hermits. It was fine when I left but when I got home 5 minutes ago
was acting strange. I did a water change today as I do every 2ish weeks and
added the blue shouldered tang, but didn't see it harass it at all. Is there
anything I can do for him?
<Not enough information proffered here... re the size/shape of the system, its
make-up... Please read here:
http://www.wetwebmedia.com/rabbitfi.htm
and the Related FAQs linked above. Hopefully others input will prompt you to
realize more. Bob Fenner>
Timid Rabbitfish - 01/26/06
Hi Crew,
<<Hello!>>
Thanks for all the info on your site and answering the questions thrown at you.
<<Happy to be here/help.>>
I purchased a 3" Barred (Scribbled) Rabbitfish (S. doliatus) a
little over a week ago.
<<Ah yes, an attractive fish...and one of the better choices for captive keeping
with a maximum size of about nine inches.>>
He shows no signs of ill health and seems to have a decent amount of meat on his
bones considering transit (no pinching).
<<A good sign, these are robust-bodied fish.>>
He is fairly active in the tank if I watch from a distance
(note from a distance). The problem is that he is so scared of me that he is
missing all of the feedings because as soon as I approach to feed he goes into
panic mode and hides.
<<Likely a behavior that will pass.>>
He is not per se refusing to eat; if food goes the way of his hiding place he
happily gobbles it up.
<<This is good...>>
Also when watching from afar I have seen him naturally grazing a couple of
times.
<<More good news...>>
Because of this I am not sure the normal course of action for
difficult feeders (i.e. soaking food in Extreme Garlic or other
additives) will help.
<<No...not the issue here.>>
He seems to want the food, but is afraid to go out and get it. I have tried
SpectraLife pellet, Ocean Nutrition Formula Two Flake, Mysis Shrimp Cubes, and
Seaweed Select Sheets.
<<All fine choices.>>
My wife fed once while I was at work and he ate, but this success cannot be
duplicated by either of us. Do you think that he will eventually become more
bold and eat?
<<I do...but for now you might do better to dump the food in the tank and walk
away to let the Rabbitfish come out to feed.>>
Is it common for this species to be so scared that they allow themselves to
waste away?
<<Common, no...I have found these fish to be quite bold/personable for the most
part. But fishes are individuals too, and will often display differences in
behavior among the same specie. And being placed in new/unfamiliar surrounds
can be unnerving for anyone.>>
I have tried to do a lot of research on this species, and while there is a lot
of info on Rabbitfishes generally, information seems to be scant on the
Doliatus.
<<Really? A Google search on the full scientific name (Siganus doliatus) seems
to turn up a plethora of hits. Though only time will divulge if there is any
real info among them.>>
Is there anything I can do to acclimate him to human involvement? (i.e. more
contact with the tank, try to stay away from tank other than feedings, etc.)
<<I would go about as normal (other than my recommendation to move away from the
tank at feeding time, for now), the fish will adjust to your presence/activity
in the room.>>
My system is a 144 gallon Oceanic half circle reef tank with 160 lbs. live rock,
20 gallon sump with wet-dry filtration, Euro-Reef CS 6-2+ skimmer, and a
powerhead for additional flow. Other
fish occupants of the tank are 1 3" Yellow Tang, 1 2" Banggai Cardinal, 6 2-2.5"
Green Chromis, and 6 damsels. The tang and the Rabbit sparred for a few days,
but everything has calmed down.
<<Not atypical.>>
Does it sound like this fish is in a pattern that cannot be broken or is there
still hope?
<<Tis hopeful.>>
Thanks in advance for any response you can provide.
Jason
<<Regards, EricR>>
