Longnose Hawkfish Snout/Jaw
Issue? 11/28/2007
Good morning all,
<David>
I'm frustrated...
<... the calm before the storm?>
Last December, I set up a 200g FOWLR tank with a deep sandbed (approx 5"). My
salinity stays pretty constant at 1.025, temperature at 26.5 - 27.5oc, my
water flow is 18X/hr.
Water parameters are all in check except Nitrates stay consistent at 20ppm.
<Okay>
I have a 28" Snowflake Moray, a Magnificent Foxface, Banded Serpent Star, and a
Harlequin Tuskfish remaining in the tank. I wrote to Bob a few times in
September when my two Bannerfish mysteriously disappeared and were found in my
eel's lair. Both fish were aggressive feeders and seemed healthy aside from a
few odd behaviors from time to time. The odd behaviours were consistent over the
5+ months that I had them and figured if it was a problem, they would've
perished earlier. The ReefCentral Community believes that it would be highly
unlikely that the Snowflake would have caught and killed these fish, but likely
scavenged on the corpses.
<I agree>
Anyhow, we've discussed this before. I wanted to comment on my longnose Hawkfish.
I purchased a longnose Hawkfish in late September. He was always curious and an
aggressive feeder who liked to play 'keep away' with my Tuskfish (i.e. grabbing
food and running swimming like mad to ensure the Tuskfish didn't steal it from
him). About 2 weeks ago, I noticed a small bump on the very tip of my Hawkfishes
snout. He was still feeding at the time. A few days later, it almost appeared
that where his snout meets his head was a little swollen. Upon a closer look, I
wasn't sure... but obviously it must've been for me to notice in the first
place? Something didn't look right. The jaw seemed inline looking at it straight
on, the fish's coloration remained bright, but something didn't seem right about
the jaw... and the fish would always keep it's mouth open a little bit, never
closing it. When I noticed the mouth open consistently... it was then that I
noticed it wasn't feeding at all... not even taking an interest in any food. The
Hawkfish would sit within inches of the eel and the eel would never bother it...
the other fish would never pay attention to the Hawkfish, however there was
usually a playful chase when the Hawkfish snapped up the last bit of food (being
chased by the Tuskfish). Anyhow, so I'd estimate the Hawkfish hadn't had
anything to eat for maybe 6-10 days. Yesterday morning, the Hawkfish lay dead on
the sandbed... I had noticed the Hawkfish gill beats per minute had increased
fairly rapidly over the prior 3 days. Are you familiar with anything that would
cause minor swelling around the jaw area of a longnose Hawkfish?
<An injury from bumping into something or being bitten>
Like I said, the swelling was hardly noticeable, but the initial bump on the
snout certainly was noticeable. I'm almost thinking that the eel mistakenly
grabbed the Hawkfish by the snout/head and realized that he wasn't desirable to
eat and then released the fish.... Perhaps leaving broken bones into the skull
and some bruising with minor swelling?
<Not likely... Oxycirrhites are smart... and fast... Perhaps the Choerodon... in
going for the same food item... or it could have "jumped", hit the top...>
I don't know... there wasn't really any discoloration around the head area and
the Hawkfish eyes would still be alert. In your opinion... what could
potentially cause the Hawkfish to keep his mouth open or possibly disable the
use of his mouth?
<See above>
It's frustrating because I started this tank with successfully keeping all of my
first 5 fish (but I did something stupid with two of them in a hospital tank and
know exactly why they perished)... but have lost my last 3 introductions without
an obvious sign of what went wrong. I'm only introducing a new one every 4-6
weeks after a 3-4 week quarantine. If fish are collected by cyanide, would it
take about 3 - 5 months to start having health problems?
<Rarely... most die immediately to within a few days to weeks>
While I have your attention, I am using RO/DI water filter since beginning of
September. I am averaging about 10g/week water change on a total system volume
of about 230g. From Dec 06 - July 07 I was using tapwater and a minor hair algae
issue that went away and I had the cleanest tank I've ever had... nice coralline
algae and only had to clean my glass once every 6 weeks. About July, hair algae
galore!!! Hence I bought the RO/DI unit. Having used it for the past 3 months
and using PhosBan for the past 6 weeks... I am noticing little improvement in my
hair algae situation. Mind you, leaving the 2xBannerfish corpses in the eels
lair vs. taking apart my tank to retrieve the bodies likely didn't help the
cause. Am I taking the proper steps with PhosBan and RO/DI ??? My lights are 95W
strip and a 65W strip for 9.5hrs/daily.

Giant Hawkfish Ailment
10/22/07
Hi,
<Hello Christine>
First of all thank you for providing such an in depth and helpful website. I
often find that the most accurate information I get comes from here as opposed
to many of my local fish stores. Anyway, after carefully searching through your
site I could not find a situation as specific as mine, with regard to my giant
hawkfish.
<Neat animals>
Let me first say that I am meticulous when it comes to water changes, checking
levels, salinity etc. So I can confidently say that the environment is not
"dirty". My giant hawkfish, who resides with his eel brother in their 100 gallon
tank has developed a very faint gray film over his left eye. It is not within
his eye but covers it. Nowhere on the body are there any other signs of
infection, or fungus, or whatever it may be. The closest thing I could find
online as far as descriptions go is something called cataracts. Well, I first
thought it was a fungus but now I am quite uncertain. It was suggested to me
that a brief freshwater dip will cause this film to simply fall off after
awhile. I did that for about 2.5 minutes and I have yet to see any change. My
hawkfish (Chad) is still as personable as ever. He eats, swims and behaves
normally. I am worried about this thing over his eye. It is almost cloudy but
again, not inside of the actual eye. I was also recommended Rid-Ich as a simple
solution but based on the material on this site, it seems as though Rid -Ich is
not so simple and will cause more harm than good.
<Agreed>
I have live rock and live sand in the tank and I have no quarantine tank to use,
so my choices are limited. Well, I hope I have provided sufficient information.
It's not so much an emergency as it is a motherly concern. For now though... I
will continue with my water changes and monitoring of levels and p.h. Any advice
is greatly appreciated. Thank you.
-Christine in Ca.
<As you state, this is a one-sided involvement (unilateral)... Though Cirrhitids
are agile, fast... this one may have scratched the outer eye... Perhaps there is
an infectious agent involved subsequently... but maybe not. I would leave this
fish where it is, do your best to maintain optimized water quality, good
(supplemented) nutrition, and be patient re (likely weeks to months) self-cure
here. Bob Fenner in smoky San Diego>
Arc-eye hawk with freckles - 08/15/06
Hello Bob and friends. I really hate to do this, but I Googled and Googled.
I opened at least two threads about this. Anyway,...I have a 37 gallon column
with 30 plus lbs. of live rock with one bubble tip anemone. There's one coral
beauty,
<Needs more room than this>
a mated pair of yellow head Jawfishes, and an arc-eye hawk. I quarantine
everybody. The arc-eye had a black spot on his side that honestly looked like
pigmentation.
<Likely was/is>
Kept him in quarantine and the spot didn't change at all. After two weeks I put
him in the display, determining it was just like a 'freckle'. The black spot is
like a fleck of black pepper. It's not raised above the surface,...it just looks
like a pigmentation. Only problem now is, there's now like 4 of them on the
fish! Again these spots are not raised above the surface. He also seems extra
skittish all of a sudden. The tank is like 9 months old. ph:8.2, sg 1.022,
nitrite:0, ammonia:0, nitrate:40, alk:2.2. Please help!
Adam B.
<Mmm, I'd raise your spg and alkalinity... Could be still some sort of
melanization... from... who knows? The anemone's presence? Overall stress of
captivity? Harassment from the Centropyge? The Opistognathids? I would not
"treat" per se. Bob Fenner>
Re: arc eye hawk with freckles (more) - 08/15/06
(continued) I also performed 3-4 freshwater dips for about three minutes
before moving to display. When the hawk was in quarantine I treated with a
formalin based medication called 'rid ich'. This was for about 5 days. I
thought maybe it was Paravortex
<Could be... but where would this come from? Has been recorded on about 125
species of five families... but this turbellarian has a direct life cycle...>
or some sort of subcutaneous parasite. I have since removed him the main display
and now he is acclimating to the qt's water. Temperature in main display is 80.
Also, I wanted you to know he still eats like a pig. Even as early as an hour
before I removed him, he was attacking the frozen Mysis with a vengeance.
thx
Adam B.
<A bigger tank... time going by... Bob Fenner>
Re: arc eye hawk with freckles (more) - 08/15/06
So, my only question is,...do I leave in qt?
<Mmm, no... not indefinitely...>
He obviously hates it in qt. I don't think he feels secure. The first time and
this time around. If I should leave in in qt,.. how long?
<Let's cut to the proverbial chase... this species, family's members need to be
housed in larger quarters, not with shrimp... see WWM re...>
If it was Paravortex wouldn't it have fallen off and also the 'spot' would go
away?
<... not likely parasitic... If this flatworm could persist for weeks...>
I have a 90 gallon that's running fallow due to ich. As with any fish that's
starts to 'outgrow' the 37, they will be promptly relocated.
<Oh! Good>
But, back to the hawk, I don't want him to stay in qt unless YOU or one of your
people say so. You're the man Mr. Fenner.
<Heeee! We're the fish men!>
'The Conscientious Marine Aquarist' is a incredible book,...thx
Adam B.
<I would try to hold off on returning this Cirrhitid to the tank with the small
crustaceans... and place it in the larger tank when it's "ready"... and not
worry re the black spots/freckles. BobF>
Re: arc eye hawk with freckles (more) 8/16/06
Well the only problem with waiting on the 90 gallon is that I still have
like 3-4 weeks until it's 'safe'. And the hawk won't eat in the qt.
<Try a grass shrimp...>
He didn't the first time around either! As soon as I put him in the display
(initially), he was eating like a maniac. You had said something about 'housing
with small crustaceans',.... I don't have small crustaceans. Just some hermits
crabs,
<...>
I feed frozen Mysis. Maybe that was the misunderstanding. So, back to the
original question,... can I put him in the display temporarily until the 90 is
ready?..
<Back to the orig. resp.>
You said 'no, not indefinitely' about leaving him in qt, isn't that like saying
yes and no at the same time?!?? (very slick.. lol)
<Sorry for the confusion... mean/t, "not indefinitely in the quarantine>
And you also said 'if this is flatworm it could persist for weeks', do you mean
it would stay visible on the fish?
<... yes>
To the best of your un-ending fish knowledge you think it's not likely
parasitic, and I agree, but why??
<Not expressed as such... not likely on the one host...>
I'm a fiend for fish smarts,...I work at a LFS, so I like to know the 'WHY''s.
Thanks
again,...I'll do my best to leave you and your crew alone for a while.
Adam B.
<Heeee! Be reading, chatting. Bob Fenner>
Re: arc eye hawk with freckles (more) 8/17/06
Well, I really thought I'd be leaving you alone, but,.. the damsel in the qt
(waiting to go into the 90) is now showing similar spots!
<Unusual>
So, obviously the hawk is staying in qt. Now my question is, did the damsel get
ti because of the less than optimal parameters in qt.... because I don't see
spots on anybody in the main display. Maybe because of the close quarters? I
feel horrible! Should i be worried about the others in the main display? I'm
going to go ahead and treat qt with a formalin based med., regular dose?
<Mmm, I would first try a simple/r pH adjusted FW bath... detailed on WWM...
under "Dips/Baths"... and see if these blackish spots "fall off"... as in
Paravortex... I still have my bet on these being "stress markings"... and would
NOT subject the fish to Formalin exposure>
Am I losing it??...
<Perhaps temporarily>
Could the black spots still be something else?
<Definitely>
How quickly things can turn into a nightmare.....?!
thx
Adam B.
<Ten deep breaths... a long walk... the letter in your sock drawer... Bob
Fenner>
Re: arc eye hawk with freckles (more) 8/18/06
Could the marks on the damsel be bite marks from the hawk?
<Mmm, yes>
...You know how damsels always 'tail-slap' new additions ...?
<Some, yes>
....Maybe the hawk retaliated?....Tried fw dips on the fish with no
luck.....jeez.....Adam B.
<Then not Paravortex... I'd take a "chill pill" here... wait on any/all "med.s".

Sick Long Nosed Hawkfish 7/19/06
Hello!
<Hi there>
My husband and I recently stumbled on your site and have found it to
be incredibly helpful. Thank you all for your hard work.
<Welcome>
I'm writing concerning our long nose hawkfish. We've had the hawk for about 5
months now, and everything was fine until recently. The hawk has been in
our 90 gallon tank. It had been our reef only, no fish tank until this year.
We were down to a variety of mushrooms and a small clump of star polyps, so we
decided to add some reef friendly fish. We added a Maroon Clownfish,
Diamond Watchman Goby, Algae Blenny, and Hippo Tang.
<Okay>
We've been battling a low pH and alkalinity problem in all our tanks
since moving to our new house. It seems to be due to the composition of
our water
here, which is not ideal for aquariums.
<Ahh...>
We've now got a R/O unit which mostly helps. We've been using Seachem's Reef
Builder and Reef Buffer to correct the problem.
<Good products>
Long story short, a little while ago (a month maybe), I noticed that
our hawkfish had what appeared to be a small bump on the lower part of
its mouth.
We worried at first that it was an injury from jumping or running into
something else. We left him alone to see if it would heal.
<Which is what I would have done as well>
It has not gotten better, instead it has gotten bigger. The hawkfish was
eating fine. When we realized that the problem was worse we put the hawkfish
into our QT tank to be
able to observe and to feed it without competition from the other fish in the
tank.
We were gone this past weekend and came home to find that part of the hawk's
lower jaw seems to be missing and it is having trouble catching the bits of
food I put in the tank. It is still active, curious about its surroundings and
coming to the surface to see what food I put in the tank.
Is it possible to diagnose what is wrong and save this fish or is it more humane
to euthanize the fish at this point? I really don't want to see it suffer.
<I am almost always siding on treatment and holding out hope...>
Other than the now corrected pH and alkalinity problems, the rest of our specs
are within the normal range.
Can you help me identify the problem?
<Maybe. Could be a long-term internal disorder... genetic, even parasitic...
perhaps a nutritional deficiency of some sort... I'd strongly consider even a
tumor resultant from a physical injury.>
I'm happy to provide and additional information that you might need and even a
photo, if that helps.
Thank you very much!
-Jen
<Pix are almost always of help... I would maintain this fish at NSW water
conditions, spg of 1.025, soak its foods in a vitamin, HUFA and iodide prep.

Re: Angel (medicine poisoning) disease?
I'm sorry to bother you with this question, I've searched the site for a
while
and couldn't find a answer. I had a dwarf flame angel, a small Koran angel
and
a small hawkfish in a 30 gallon quarantine tank. Is it possible for the 2
angels in a quarantine tank to get a disease, and not the hawk?
<Yes>
The two
angels
eyes became very cloudy. I was treating the tank with Maracyn 2, Maroxy and
Coppersafe.
<<... how much of all this?>>
Both angel's eye's seemed to just waste away leaving what seemed
to
be two blind angels. After removing the two, the hawkfish seems fine. It has
been 4 days since taking out the angels. I've read some things about angel
disease. Is this what happened?? <Angels can be a little sensitive to
copper. Did you monitor your copper level with a test kit? The recommended
level
would be 0.15ppm. Another problem is too many medications in the tank at one
time. Determine the disease and treat for that disease only. James (Salty
Dog)>
<What? Where's the previous correspondence? There are some three dozen of us
"here". Bob F>
Thanks for the quick response. The copper level was at .15ppm, My main
question wasn't answered though. Is it normal that the 2 angels health was
horrible
while the hawk seemed, and still to this day is seems fine?
<Cirrhitids can be remarkably disease resistant compared to Angels. Bob Fenner>
White Fecal Matter
Morning Bob,
<Scott>
I have a question regarding a Dwarf Hawkfish (Cirrhitichthys falco, I believe) which I recently moved into a QT. I was running a 39 gallon Eclipse
3 as a FOWLR tank for 4 years. That was until my wife got pregnant and decided to turn my fish room into a nursery!!! I was able to adopt out all
of my specimens except for this one hawkfish. So I set up a 10 gallon Eclipse 1 and cut the material Bio-Wheel down to size to fit the Eclipse 1
Bio-Wheel, to avoid a new break in period. I also transferred 5 gallons of the water but none of the LR or Substrate. So the tank is clean except for 1
piece of bleached coral for hiding. I also moved a few bumble bee snails, and Mexican turbo snails with the hawkfish. This was not meant to be a QT
tank for health reasons, so no meds were planned on being used.
Since moving into the new tank, the hawkfish stopped eating immediately and breathing
became heavy. All water parameters (e.g. pH, salinity 1.023, temp, alk) are exactly as they were in the main tank.
Three days ago, while performing a partial water change, I saw a little white worm wiggling around on the glass
bottom of the tank, so I quickly sucked him out with the hose, not thinking to try to save it for ID. About a day after that I noticed my hawkfish had
white stringy fecal matter and was still not eating. When I woke up this morning, I noticed that he has the beginnings of
Popeye disease. I have the
full range of meds (e.g. copper, MarOxy, Formalin-3, Maracyn I and II), however I'm
not quite sure how to treat. I know that I have to remove the snails, no biggie there. Any help would be fantastic.
<If anything I would try a dose of Metronidazole/Flagyl... this is described on WWM's root/marine web. Bob
Fenner>
Longnose Not Doing Well
>Hi, I am hoping someone can help.
>>Hello.
>I have a longnose hawkfish. I noticed he was not eating as well
as he does normally. I also noticed he was perching a little crooked
on the rocks. Now I have noticed his left eye is bulging out. Do
you think he got hurt, or could it be some sort of disease.
>>One eye tends to be from injury, if it were disease it would present
equally and bilaterally.
>Should I quarantine him? Any advice would be helpful. Thanks
Debbie
>>You may wish to figure out who/what is causing him injury. In
the meantime, it may certainly be the case that, until you get it sorted, q/t is
best. Marina
Longnose Not Doing Well - Follow up
>Thanks for your prompt reply. I don't know who would be
bothering him. I only have a 35 gallon tank, with 5
fish. I have had him since October, and have seen on bullying from
other fish. I guess I will try QT him, maybe he will recover faster,
if he does not have to fight for food. Debbie
>>Ahh.. this is telling. Longnose hawks, as you may very well
be aware, are known jumpers. I am guessing that in such a small tank
he may have hurt *himself*. In which case, there's likely no need to
move him, but you might wish to consider future digs for him, especially if this
occurs again. Marina
Flame Hawkfish
I have 29 gal tank with a maroon gold stripe clown
fish, purple Dottyback, eibli angel, and a flame
hawkfish. I had recently used MelaFix to fix to the
tail of the clown who looked like he had been picked
at. But this made the water kind of filmy looking so I
put activated carbon in the media tray of my emperor
280 to try and clear the water and this seems to have
worked wonderfully. Except that my Flame hawkfish is
now hiding in the rocks, and is always on his side. He
just sits there when the other fish come over and poke
at him and really doesn't seem to be eating.
<Doesn't sound good. Just sitting there is no big deal... but the other
behavior...>
He used
to sit on the powerhead in an upright position all the
time, but now will only stay crammed up in the rocks
on his side. Aside from the charcoal to clear the
water there have been no changes and the other fish
seem much happier since the charcoal went in. Is this
normal for a hawkfish or should I be concerned.
<I would be concerned. I would execute a large water change (25%) and try a bit
of live food... best, some live Glass Shrimp... perhaps soaked in an
appetite/vitamin enhancement product like Selcon. Bob Fenner>
Thanks for any help you can give me,
Jim
Re: Flame Hawkfish
Bob,
<Jim>
Thanks for your advice, but he still died today. When
I first bought him it was about 4 weeks ago and he
didn't seem all that active in the tank at the store.
<... sounds like cumulative stress, damage from collection, shipping...>
And against my better judgment I let the store worker
talk me into getting him because they said his colors
looked good and I had read that they were supposed to
be a very hardy fish, but it turns out I may have
gotten damaged goods since my other three fish, which
I bought from different pet stores, are all doing
well.
<Think so. Bob F>
Thank you for your help,
Jim Kinney
Re: Flame Hawkfish
Bob,
Here is my last question of you on this. I'm not going
to get anything to replace him for at least a couple
of weeks,
<And hopefully he will reciprocate>
but I wanted to keep the number of fish at
4. And I wanted to know if a flame Hawkfish is
actually a good fit with the fish I currently have.
Because this one had labored breathing from the day I
brought him home and I wanted to know if that was
their way or again just the built up stress?
Thanks for all your help,
Jim
<Uh, Jim... what are the other specimens? Only time can/will tell whether this
Hawkfish rallies. Bob Fenner>
Sick Hawkfish
<Beth, I'm sooo very sorry for the delay, I just got this today. Hope
we aren't too late. MacL>I have had a banded Hawkfish since 9-16. The store
had him for 4 weeks and I put him in qt for 2 weeks. He has always been a great
eater. I feed him flakes and fresh shrimp. About 3-5 days ago he spit out his
shrimp and hasn't eaten since. He seems to have raw areas around his mouth and
part of his lip is swollen and red. <That doesn't sound so good> I don't
know if I'm imagining it but he seems to have white patches around his
gills...maybe just natural markings I don't know if I'm paranoid or not.
<Could be or it might be some type of fungus. Very possibly might be where
he's knocked into something.> He also has small white dots all over his nose
and above his eyes...again maybe just natural markings. <Those probably are
natural.> The only med I have is rid-ich and I live in a rural
area and must travel to get anything else. I have moved him to the qt. I tried a
freshwater dip but he went into shock so I put him in the qt without it.
<Lots of times when they are being freshwater dipped they will lay on the
bottom and look pathetic but that's actually typical of fish in the dip.> He
is still active and "plump". I put in a dose of rid-ich as it says it
will kill fungal and parasitic infections. It will be Saturday night
before I can get anything else. I had allowed the main tank to get away from me
and amm and no2 was 0 but no3 was between 40 and 80. the qt is stabilized and
amm and no2 is 0 and no3 is 15. ph stays a constant 8.2 and temp is 78 in both
tanks. s.g. is 1.024 he is the only fish in the tank aside from a choc chip sea
star who is thriving...surprising considering the no3. <You definitely need
to do water changes to get that more stable. I have had excellent success with
MelaFix in my saltwater tanks for this type of problem. Please write me back and
let me know what's going on with him? Good luck, MacL>
any help, please
Beth
Hawkfish On The Mend!
Thanks for getting back. I know you all get a lot of mail.
<Scott F. following up tonight!>
"Spike" is still in the qt. He just finished a round of Spectrogram.
There was definitely white
patches on his side that was obscuring his stripes. Same with the raw patches
around his face. The Spectrogram has worked great. the blister below
his lip is going away. it is now just a red spot on his lip about 3/16 in. long.
He ate some fresh shrimp yesterday and is once again swimming very well. The
Spectrogram apparently killed my biofilter in the qt, so I am doing daily 2 gal
water
changes.
<A good help in this situation. You may even want to limp the biofilter along
with a "bacteria in a bottle" product for a while...>
I still have a few questions... do I wait another day and do another round of
Spectrogram as the package suggests, or run carbon for a day or two and try a
different antibiotic.
<I'd stick with just one medication, especially if it is working. Always
follow manufacturer's suggestions concerning dosage and duration, unless you are
noticing very negative reactions. Just keep monitoring water quality and begin
using carbon and water changes when the next round of medication is
complete.>
I do have Melafix, but was told it is not effective.
<Perhaps it is on some conditions...I'm not a big fan of it. And again, I
would not mix medications at this point.>
And now that he is eating, should I go back to his regular every other day
schedule or daily to help him get stronger.
<I'd go for daily, with attention to water quality, of course.>
I usually give him a few flakes and about 4 small bite sized pieces of shrimp.
<Try some really nutritious items, like Mysis Shrimp, which can really help
provide the nutrition that he needs to get stronger...>
Thanks again for all your help, Beth
<Sounds like you're doing a great job, Beth! Keep it up! Regards, Scott F>
Flame hawkfish losing color 3/1/05
I have a 125 FOWLR with 130lbs of rock and ample skimming and circulation. About 4 weeks ago, I added a flame hawkfish to the tank. He was bold red, active and eating well, basically an excellent specimen. Since joining my tank he has continued to be active and eats well. Tank gets a variety of foods (saltwater multipack--4 different foods, plus
Mysis shrimp, zooplankton, romaine lettuce, broccoli, and flake, making a diet of 9 foods
in addition to whatever is on the rocks).
<do emphasize crustaceans in this fishes diet... principal prey and also color enhancing. Add some Cyclop-eeze based foods too for value and color>
The other occupants:
Yellow tang
Juvenile blue angel
Foxface
Royal Gramma
Sixline wrasse
Chalk bass
Ladder glider goby
Purple firefish
Green Chromis
Percula clown
The hawk has always appeared to get along with everyone, and I have not noticed any obvious stress. For the past few days, his color has been fading. He is still eating, but he spends more time on the bottom rather than hopping among the powerheads and rocks. He just doesn't look healthy. Any ideas why he is fading? What should I do?
<it could be impending illness... do look for symptoms. It could also be light that is too bright or substrates that are too light. 4 weeks is not long enough for diet to be the reason, though. Do examine the previous suggestions. Kindly, Anthony>
Hawkfish illness
5 days ago we did a 12 gallon water change on our 55 gallon tank (we do
these weekly). In the tank currently are 2 domino damsels and a falco
hawkfish. We also have converted to power compacts (4 55's) and have finally
been leaving all four lights on (rather than just for a few hours for the
adjustment period) One day later (after the water change) the hawkfish was
hiding out in our live rock which was strange for him. But, he was still
eating and looked fine so I thought he was okay. He is not eating now and
acts almost dead, but still breathing. He looks at the food as it is
offered, and notices it, seems interested but does nothing. His fins are not
clamped, his breathing is normal and his color is good. He does look
skinnier though. Also, it seems like he is not "with us." Plus, he
never
comes out from under the rocks (he is usually all over the place) I did
another water change as we had used a buffer for the replacement water last
time. I am thinking he got poisoned by supplements. Here is my problem...I
would like to quarantine him, however my quarantine tank is occupied by a
Sailfin tang I purchased about a week ago, (before this all happened).
Should I place my hawk in there anyway? Should I just let the hawk hang out
in the main tank and 'hope' this all blows over? Could this be related to
the lights at all? (Too bright?) Would quarantine help if he has been
poisoned? (or something). He just acts brain dead, and usually he is such a
character-coming up to the tank to let us feed him when he sees us, etc. So
this is very upsetting. BTW all my testing levels were normal. Thank you in
advance--Carolyn -just when I thought I was getting this all down...>>
Hmm... something is awry with your Hawkfish... it might have something to do
with the supplement (maybe he got a strong dose, ate some?), but not the
lighting as a factor..... And I would just leave it in the main tank and hope
for the best... Not worth the trauma to all (including you) trying to catch
it... possibly upsetting the Sailfin Tang... versus what might be gained.

Hawkfish
Hello,
I have a 72 gallon saltwater tank with a porcupine puffer and a maroon clown.
These were the only fish because of an outbreak of ich. I bought a 20 gallon QT
tank (unfortunately after the outbreak instead of before) and left the 72 empty
except for live rock and sand for six weeks. I then put the puffer & clown
back in the 72, everything seemed to be fine to this point. We then bought a red
Coris wrasse and a red flame hawk and put them in the QT tank for 2 weeks.
<A little short, I prefer a full four weeks just to be sure.>
They seemed to be doing fine with no signs of disease. I added them to the 72
tank and on the 27th the next day the hawkfish was dead. I did notice his color
seemed pale when we first put in the larger tank and he literally dropped to the
bottom instead of swimming, but his color seemed to come back soon after and he
was perching on rocks soon thereafter. The wrasse is doing fine, but I'm in the
dark what happened to the hawkfish. We were told they were very hardy. I do need
to mention that the water checked out fine in both tanks before we bought the 2
new fish and the temperature and salinity are identical. The 72 tank is about 6
months old. Any ideas? Should I do different in the future, maybe treat any new
fish with copper just to be sure?
<Because of the fast nature and lack of symptoms we can probably rule out a
disease as the cause of death. I would instead double check the water quality in
the 72 (perhaps at a LFS with their test kits) and also look into your
acclimation procedures when you released the hawkfish. -Steven Pro>
- Mystery Spot -
Hello,
<Good morning, JasonC here...>
I have had Snarky, a Long Nose Hawk, for approximately one and half years.
Tonight I noticed, for the first time,
this black spot on gill next to his eye. I netted him, and he let me
attempt removing the spot, but it would not
come loose, as if there was nothing clinging to his body. I can not
tell if it is Turbellarian, or if he had
developed a beauty mark, that I just happened to notice after all this time.
I have attached a good picture of the spot I am referring to for your examine,
and I can magnify this picture, and
resend it if you need a closer view of it. I would appreciate if you
could let me know what your assessment is ASAP,
so I can begin treatment if required. <I think this is most likely something
similar to a bruise.> I am also scheduled to
leave on vacation this Friday. It always seems that stuff like this happens
before I go on vacation. <Ain't that the truth.>
Anyway, my tank is very healthy, and I don't suspect this to be an illness,
since Snarky isn't exhibiting any loss
of appetite, scratching, or listlessness, it's just that it seems like an
unnatural marking amongst his red and
white pattern. What do you think? <I think it will be fine - will
go away in time.>
Thank you for having such an informative site/resource for an aquarist to
improve their fish friends'
health and well being.
Sincerely,
Joel
<Cheers, J -- >
- Single Black Spot -
Hello,
I think I missed your assessment. Should I be concerned or not?
<It's my opinion that the spot is just a bruise. No cause for concern.>
Thank you, Joel
<Cheers, J -- >
- Another Follow-up on Freshwater Dips -
Would you consider Longnose hawkfish a fish? <Of course - it's certainly
not a bird or a horse.> The ich seems never affected it. <They are just
durable and disease resistant.> Would you recommend a cleaner wrasse for the
tank since it feeds on external parasites? <No. Please read here:
http://www.wetwebmedia.com/labroide.htm
> I bought one last weekend because I had seen them servicing the
fishes, hoping this one would perform the same function. Yet this new
wrasse never approached/touched the fishes w/ ich. <Is probably getting used
to the new environment.> Is that strange? <Not really.> I wonder if the
ich on the fishes scared the wrasse away. <I doubt it. Cheers, J>
Disease ID
Hello Crew,
I have an Arc Eye Hawk (Ivan's his name) that 2 times over the last 6 to 8 weeks
has had small, white nodules (for lack of a better description) on the front
spines of his dorsal fin. They look a lot like small pieces of
Styrofoam (and having recently battled Ick it looks nothing like
it). The first time, they went away on their own, leading me to
believe that something (some debris) got stuck on him. He got them a
second time and as of yet they have not gone away (after about 7
days). He is otherwise active and eating really well. Do
you think he has some funky disease and if so what is the
treatment? All other fish in this tank (a 180g FO) are healthy and
eating well. Any insight that you can provide would be greatly
appreciated!

<Hey Bob, it is hard to say with out a picture, does it look fuzzy? Check out
the disease sections at the link below, see if any of that sounds familiar
http://wetwebmedia.com/marine/maintenance/index.htm
If he is infected with something, the first step would be to get him into a
quarantine tank for further observation and identification of the
disease. Feel free to send a pic if you can. Best Regards,
Gage>
