Horseshoe File fish (Meuschenia hippocrepis) hardiness? 9/22/08
Good day to you Crew! <And you April> I have searched your FAQ's for this
amazing fish from Australia, but have not seen a mention of it here. I am
writing to thank you for all of your volunteer time for us, it is appreciated,
and to ask if you know about this fish's hardiness in the aquarium? <Mmm, I
don't know if I've ever seen this species here in the west... Maybe caught a
glimpse of it diving my only trip to Tasmania... Ran a Google search with:
Meuschenia hippocrepis in aquariums... Has been kept...> I have learned as
much about it as I can with the little I could find on line, and really love
it so far. The final piece of information I need to make my decision, however,
is regarding its hardiness in the aquarium. I am considering its purchase, high
price and all, but do not wish to purchase anything delicate. I understand
it is considered peaceful, can grow quite large, 20" max, and would need at
least a 200 gallon home. I have a 300 gallon FO+LR set up, at 8 ft. long. I
have a 7" Naso Tang, two butterflies, seven yellow tail damsels, and two
cleaner shrimp. Thanks a ton for all you do there! April. <Mmm, not
really an appropriate choice as this animal is really coldwater/temperate, and
your present stock/system is tropical. Bob Fenner>
Bad idea? Filefish sel. 4/25/07
Dear Bob,
<Stefan>
My marine aquarium has been running for almost 2 years, deep sandbed, plenum in
the main tank (1.2m) In total the system consists of about 350L of water.
I have 3 clown fish, 1 regal tang, 1 blenny, 1 cardinal. All fish relatively
peaceful. I also have a variety of mushrooms, Ricordeas, zoanthids and some
leather corals
I was thinking of adding a trigger fish, but they grow far to big for my liking
and they will eat the hermits, shrimps etc..... Now I'm thinking Filefish. I did
some research and it seems that the Redtail filefish (Pervagor melanocephalus)
would be the only choice for a reef system. Do you agree with this statement?
<There are a few others... Most Monacanthids are found on or associated with
reef environments...>
Any other species of filefish to consider adding to my tank?
Thank You
Stefan Dorfling
<Not really... Your system is too small. Bob Fenner>
Black Saddled Mimic Filefish
Dear Scott F:
<Hey there, Connie!>
I read a letter today from someone named Rich who recently bought one of the
above. I have been waiting for about three months for this fish and
cannot locate it. Is there some way Rich could let us know where he
bought the fish? If he bought him on the internet or he lives
near San Francisco, I would love to know.
Patiently waiting. (ha) Connie
<Well, Rich- can you help out a fellow Filefish enthusiast/WWM supporter
here? If Rich isn't in your area, you may want to check out Marine Center (see
the link at the top of the page)...They can often obtain rare and unusual
specimens for you. In fact, I can mention at least two occasions where I was
looking for something that they didn't list at the time, and they actually
emailed me a couple of months later when they finally received it! That's good
service! Hope you find your filefish! Good luck! Regards, Scott F>
Longnosed Filefish
Hi,
<Hello>
I know this fish is hard to keep, and usually dies within a week.
But, if
this fish is provided with its exact needs would it live a much longer life?
Yours Faithfully Aaron.
<Of a certainty yes. There are a myriad of factors that go into an equation
of likelihood of survival/mortality... species specific, size, sometimes sex
influenced aspects... for relative resistance to capture, holding, moving...
feeding response to whatever (if anything) folks are offering... In this case,
this species does hold up pretty well to being caught, held and shipped, but
most often is "stuck" in situations/circumstances of too small a
space, not enough maturity to the system, too many more-aggressive feeding
tankmates... and most especially a lack of appropriate foodstuffs. Improving on
all these aspects/factors and more definitely improves ones chances of keeping
this fish longer, healthier... even to and through reproduction. Bob Fenner>
Long Nose Filefish...NOT! For Captive Keeping - 02/13/06
Hi there!
<<Hello!>>
I am just curious if someone could answer a question about a long nose filefish?
<<Ah yes, Oxymonacanthus longirostris...beautiful and interesting little
fish...and completely unsuitable for captive keeping.>>
I recently bought one and yes I knew that they would be hard to feed.
<<(sigh)... More like impossible.>>
The one I have seems to be doing great,
<<Doubtful my friend.>>
I have many different foods both frozen and liquid form <<!!!>> that I was told
it would eat, and that simulate what it would eat in the ocean.
<<Someone is sadly misinformed...or lying to you. Either way, no excuse for you
not doing your own research BEFORE buying this fish. Oxymonacanthus
longirostris feeds almost exclusively on Acropora polyps...unless you are
prepared to buy live corals for this fish to feed upon, it is doomed.>>
Anyways, since he has a long snout with a hole on the end of it and his mouth
does not move, how can I tell if he is eating it?
<<Mmm...you state the fish "seems to be doing great" yet you don't know if it is
feeding...I assure you it is not likely at all.>>
Also, what would you suggest to feed it?
<<As already stated, live Acropora polyps. Your best hope is to return this
fish to the store that sold it to you...perhaps you can inform them of its
unsuitability to the aquarium trade... Regards, EricR >>
Long Nose Filefish...NOT! For Captive Keeping II – 02/14/06
Thank you for the reply, as I said I knew that it was a hard fish to feed,
and sorry for not doing my research before buying it. I just wanted to know if
you had any additional information on the fish, because what I have read in the
site from a few other owners of the long nose filefish, they have had luck with
feeding.
<<But what constitutes a "few"? One in fifty?...a hundred?...a thousand?>>
And to make you aware I think that it is feeding due to its activity when the
food is in the tank and it swims from one side to the other very fast which I
thought meant that maybe it was swooping it in to its mouth.
<<Why would you think this? Have you actually seen this fish ingest food?
(apparently not, according to your previous email) Have you done any research
on the feeding habits of this fish?>>
And on a side note I do know that you guys know a lot about the fish and that is
why I contacted you, I did not need your response to be so rude,
<<No, wasn't meant to be rude, but 'was' meant to be matter of fact/to make a
point.>>
by saying it was my fault for not doing research, and that when I said my fish
was healthy looking you replied that I must not know that because I do not even
know if it was eating.
<<Please keep your facts straight... You didn't say your fish was "healthy
looking", you said your fish "seems to be doing great"...and you did also say
"how can I tell if he is eating it?". A fish that is not eating is not "doing
great"...and this fish specie is notorious for "not eating". And...if it is not
your fault for not doing research beforehand, whose fault should it be?>>
It actually seems that you do not know the information to tell me because you
did not answer my questions you just had a smart remark to give me about every
sentence.
NOT INFORMATION. Thanks for the help but for the curiosity of the others
needing your help you might not want to be so rude when responding to people
just seeking your assistance.
<<Is unfortunate you view it that way/that I wasn’t able to tell you what you
“wanted” to hear. Regards, EricR >>
Orange spotted filefish... Alive! 2/7/06
Dear Bob,
<Terri>
I am a long time reader but a first time emailer so please be gentle! I have had
a success where many others fail, so this is my one and only chance to
brag; plus I thought that you and others might be interested in this. I am the
proud owner of an orange spotted filefish that has just past the 18 month mark.
<Congratulations!>
He, (well I assume he is a 'he'), lives in my 75 gallon seahorse tank with 8
horses and a long nosed hawk fish. I know that you are not going
to believe this, but he consists solely on a diet of frozen foods.
<Have seen this>
This includes Hikari Mysis, Marine Green, Marine Dinner, Frozen Squid and
occasionally as a treat, live brine. Additional to this, he picks at a strip
of Nori I hang in the tank. Attached are a couple of pictures showing how
healthy he is. I keep meaning to borrow a video camera so that I can make a
short film of him eating the frozen food and send it to you (if you are
interested). It is amazing watching him eat the Mysis through his long
tubular snout. I am religious with my water changes, tank maintenance and have a
skimmer, chiller and U.V. sterilizer. I am not encouraging novice
reefers to try to keep this fish, but I just letting people out there know that
it is possible. This is my first filefish and he is definitely my pride
and joy! I love him more than my seahorses and that is saying something!
Hope you found this interesting,
Terri Rennie - (Sydney, Australia)
<Thank you for this input. I do suspect that your success is due to the peaceful
setting, good care you've provided... and the initial good health of your
specimen. Cheers, Bob Fenner>

Tassled Filefish, sel., comp. 8/20/06
Thanks for the great service you provide. You have helped me and countless
others.
<And greatly enjoyed most moments...>
I have a compatibility question. I lost a beloved lionfish a few months ago who
was the star of the tank. I would like to
add a fish with similar star quality but want to avoid the feeding issues I
experienced with the lionfish. (The lionfish would
begrudgingly eat frozen silversides and krill but I had to separate the other
fish to give the lionfish enough peace to eat.)
<Yes... a common scenario>
I'm considering adding a Tassled Filefish to the tank.
<Neat animals... but do get large... need a few hundred gallons to "get around"
even though not fast moving...>
The Tassled Filefish is definitely an incredible looking fish and from what I've
read had a good temperament and is likely to accept frozen foods well. My tank
is a
250g fish only tank.
<Mmm, a good candidate thus far>
The current residents are a dogface puffer, porcupine puffer, Falco's hawkfish,
sailfin tang, striped squirrelfish, a male and female bird wrasse, and a male
and female blue-jaw trigger. My water quality is consistently good, with ph at
8.3, nitrates between 10 and 30, and kH between 10-12. I do a weekly 40g water
change and get
a cup of skimmate every few days. I feed the fish frozen silversides and krill
soaked in Selcon and garlic once daily. I also give the sailfin tang Spirulina
and Formula One Marine Pellets a couple times a day, which the wrasses and
triggers also eat. Most of the fish are pre-adult though the male bird wrasse
and sailfin tang are adult size.
Do you think the Tassled Filefish would be a compatible addition to the tank?
<It itself should be... there may be a bit of jousting, tussling at first with
the tank and maybe some others...>
Would it be able to compete effectively for food?
<I do think so... if "given enough chance" to settle in>
Would it be harassed when introduced?
<Is a possibility>
After introduction?
<Much less a probability... this species, Files/Monacanthids in general are
"left well alone"... hard-bodied, perhaps not recognized as
fishes/competitors... I give you good odds here>
I have plenty of rock in the tank, but many of the caves and crevices are
frequented already by the current residents. Your advice would be greatly
appreciated.
Thanks. Mike
<Welcome. Bob Fenner, who would start with a "mid-sized" specimen... maybe 4-5
inches overall length.>
