Filefish ID
Hello,
<Howdy>
I recently bought a red tail Filefish and was curious about one thing. Of all
the red tail filefishes I've seen on the internet, almost all of them are either
red or yellow-orange in body color (not the tail). The one I bought
is blue with a red tail. Is this normal? I've done a search all
over the net and did not see any blue red tail filefishes. Was it
mislabeled?
Much Thanks. Michael
<Mmm, this is likely Pervagor spilosoma... and some do look more blue-bodied.
Take a look at fishbase.org re this
species: http://www.fishbase.org/Summary/SpeciesSummary.cfm?ID=4373&genusname=Pervagor&speciesname=spilosoma
Click on the one image shown and this will take you to all the pix they have to
display. Click on Google Images on fishbase.org there for even a few more pix.

Delicate File Fish, Orange Spotted Filefish Question
<HI, MikeD here>
Hello,
From the first day I began my salt water hobby I always wanted to keep the
orange spotted filefish.<Neat fish, very common here> <<Umm,
there is an identification difference going on here. MikeD is referring to a
species in the tropical West Atlantic, and the querier is speaking of a
Pacific... Cantherhines
macrocerus and Oxymonacanthus longirostris respectively.
See http://www.wetwebmedia.com/filefish.htm.
RMF>> But after researching I found that this
was a very difficult animal to care for.<Not really, just not often offered
for sale> One year into my hobby my want for it has risen and I
have decided to make a commitment to getting at least one.<OK. They are
another personality fish>
For the tank that it would live in this what I plan to have.
Tank.
10 gallon<Problem #1...too small for all but a tiny juvenile. These are
active, like little "mini-triggers"
Lighting.
Fluorescent compacts. at least 200 watts)<not a problem>
Rock and Sand.
5- 10 pounds of Vanuatu rock. 10- 15 pounds of live sand.<That
part's good>
Water Circulation.
A couple of small pumps<OK>
Heating.
Brand which I have forgotten the name of.<As long as it works>
Filtration.
I plan to get a skimmer so that will be in the next month or so. Also
here is where I will need your help. What kind of filter would you
recommend for such a small tank.<One that holds less water than
the tank!**grin**>
Corals.
A mixture of Acropora corals. I plan to grow the Acropora in my
refugium on my 75 gallon tank along with the coral in the ten gallon.<AND
here's problem #2. Many filefish just love SPS almost as much as they do
anemones!>
SO how does this sound and am I leaving out anything? Please tell me
if I am because I would like this to be a challenging yet not a killing change
of path.<My suggestion is at least a 55 gal. tank w/o corals unless they are
planned as live food. Sorry, but those are the facts. Just the facts. Badge
#714>
Re: Delicate File Fish
<Hi, MikeD here again>
I only plan to keep on filefish would that be okay in the small space.
And yes the corals are for live food.<Sorry about the previous mix up, but
I'd JUST seen the Atlantic OS Filefish offered for sale for the first time just
before reading your earlier questions. In regards to O. longirostris, sadly these
are another little beauty that is best left on the reef, and can be difficult
even for public aquariums willing to spend thousands to house them. Even
though small I doubt that you could supply enough live SPS to last very long as
their hummingbird movements belie a similar metabolism to the little bird
counterparts as well. I can truly understand their appeal, but it's usually one
that always has the same outcome in a home tank, with another living gem snuffed
out in the process.>
Valentini mimic filefish 4/5/04
Connie here again.
<cheers my friend>
I see that Mary M. has a Valentini mimic filefish on hand and I am wondering if
I could put him in with my current residents in my 60 gal. tank.
<hmmm... they stay small enough (unlike many filefishes which get way too
large for even big aquaria)... but they are/can be nippy to both inverts and
fishes>
I have two b/w clowns (1-1/2 and 2 inches) an arrowhead wrasse, about 1 inch, a
boulardi wrasse 4 inches and 2 flasher wrasses, each about 1-1/2". I just
have mushrooms, no corals, LR an DSB. I have always wanted one but somehow with
all the various wrasses it seems like a strange combo.
<agreed>
All of my fish are peaceful, non-aggressive guys and DSB finally in good
condition.
<very good to hear the DSB is back on track! Back to the file, though, do
resist... they are just too nippy for most community fish or reef aquaria. Under
the best of circumstances, they will still be too slow to compete with faster
swimming community fishes like your wrasses for food>
Best regards to you. Saw Cheri again today which reminded me of your visit.

<keep well my friend... Anthony>
Blue Eyed Filefish
Greetings,
Your site has without doubt, been my best source of information. I recently
purchased an interesting fish that I'm having difficulty identifying. It was
sold as a planehead filefish (they did state they weren't 100% sure of its
identity).
<Stephanolepis hispidus?>
After sourcing information, it looks completely like a seagrass filefish
(leatherjacket) except for the fact that it has bright blue eyes. I can find no
picture or literature on filefish with blue eyes. Is there a blue-eyed file fish
to your knowledge?
Thanks, Elizabeth Turner
<There are some monacanthids with blue eyes... though my pics don't show them
well http://www.wetwebmedia.com/filefish.htm
. Maybe give a look over the images on fishbase.org for this family's members...
and their handy link per species to "Google Images". Bob

Any idea of the Identification?
Hi Bob,
<Hello John>
I ran across you on the WWW and your excellent review article on File
Fish.
<I see>
Anyway I collected the attached in the Los Cabos area of Mexico and have
been
struggling with the identification. Initially I thought it was a
Blunthead
Triggerfish, Pseudobalistes naufragium, but now think it might be some
kind of
File Fish. Do you have any ideas or can you point me in the right
direction?
<Is a monacanthid... from body shape, single dorsal "trigger"...
definitely not the Blunthead Trigger... have seen both in and about the
area... Looks like an Aluterus scriptus to me. A neat, though large for
aquariums species found circumtropically.
Appreciate any help you can provide.
John T. Snow
<Wish we were diving there right now! Cheers, Bob Fenner> |

Bob,
Thanks for the phenomenal information in such a timely fashion. I ran a
Google search of Aluterus scriptus and know you are "spot on."
<Ah, did you see any live specimens?>
Right now I am spending 1/3 of my time in the Los Cabos area, left there
two
days ago, and wish I was back there already! My collections are all
done via
hook and line.
<Neat... have spent about two years total all over Baja, many times in
and along the corridor. Would like to get down there with some
shell-collecting friends>
What I am working on is the Fish I.D. section of Mexfish.Com with my
friend
Gene Kira. We are currently conducting a "once over" of what we have on
there
before I add more species to the presentation.
<Sounds like a great project... was surprised this last year to have a
friend in common (Paul Kanner) tell me of the how of Alex Kerstitch's
demise... am sure you have seen his work in your field>
I collected the fish we are
discussing and took the photo about 4 years ago - you will see it as a
Blunthead
Triggerfish on MexFish.com at present. However my skills and abilities
in
the fish identification area have increased significantly and I quickly
realized
that I had this one WRONG.
<Naufragium is... unmistakable... especially as full size adults! They
steer clear of divers... and are not nearly as common as "sopa" fish as
the Finescale...>
Thanks for sorting it out for me and we will give you credit in our
write up
(unless you advise me otherwise).
Thanks again!
John T. Snow
<No need for credit. Make it known if I can be of assistance with
photos, what have you. A bunch of our stuff is out and about (gratis)
for non-commercial purposes. Bob Fenner> |
Filefish ID
Hello WWM Crew,
Recently I had the opportunity to visit the Toba Aquarium in Toba, Japan.
<A fantastic sight>
They had a huge reef tank about 30 feet long (I attached a picture of the tank as well as I
thought it might interest you). In it, I saw this interesting fish poking its long "nose" amongst the corals.
<It's an obligate corallivore>
I have never seen such a fish. Could you identify it please?
Thank you,
Gisho

Toby puffer identification 9/25/05
Hello Bob,
<Emily>
I was on your site and read your notes on the difference between the Toby and
the filefish. I can't
really tell from the pictures which is a puffer and which is not. I have
recently bought a Toby puffer(
valentini I think) and just wanted to verify that I got a puffer instead of a
filefish. Can you give me
more prominent signs to look for in order to tell a puffer from a file fish?
<Mmm, the very best is their dorsal fins... though not often erected, will
likely be when excited (like when feeding). The Filefish has a prominent
anterior spine (first dorsal ray), whereas the puffer has all-about the same
appearing rays>
My fish doesn't seem to have the obvious blue lines running from the head to
tail
but there is a hidden blue/green color at the back if seen at a special angle.
<Mmm, the color difference/s are not consistent, nor telling>
Appreciate if you could help me identify my fish.
Thanks,
Emily
<Look on fishbase.org, the Net... at both species... and their dorsals. Bob
Fenner>
