Ghost Knife
Hi, I recently bought a new fish from a local pet store and he is doing just
fine. The guy that sold it to me said it was a Black Ghost Knife fish, although
the fish does not have a white stripe down its back or a white band around its
tail. It does, however, have a very dark brownish red stripe where the white one
normally is and no band of color on the tail. The fish's body is jet black. Is
this a Black Ghost? If you know the answer could you email me back? Thanks!
<Hmm..., not quite sure, do you have a picture? Check out Monga bay and
Fishbase to see if you can find a match. -Gage

That's Black the Knife
Hi guys and dolls....
<Hello, Sabrina with you today>
My question refers to the black ghost Knifefish. I saw some at my LFS for $25!!
Expensive but they are really cool. Now I know they are supposed to be black
with a white stripe running down the top, and a white ring on their tail. The
LFS had about 9 of them, but some of them had a yellowish stripe instead of
white. Is this normal or are they sick? Thanks for the info.
<I've seen older ghosts have yellowed looking stripes as well as a graying body,
but when young, they should be quite black with rather vivid white markings. Do
keep in mind that this is a shy, nocturnal animal, very aggressive within its
species (one to a tank, basically), and reaches a whopping 20 inches.... A very
large tank would be quite necessary to house one of these beautiful beasts - and
no aggressive fish, nor any small fish, could be housed with it.>
UFS (Unidentified Freshwater Specimen)
Hello again, Mr. Fenner!
On my yesterday's trip to my LFS I spotted in one of the freshwater tanks, along
with some Discus, a black sort of "file fish" thin) around 2" long; it also had
a white stripe near the head and a peculiar way of swimming, since it only uses
a long ventral fin to do it. Not recognizing the species I asked the employee
the name of it. The answer was: "It's a Roberty... but that's all I know!". Can
you please give me any clue of it is, or a positive ID of this specimen???
<Umm, sounds like a "Black Ghost Knifefish" to me: Apteronotus albifrons. Please
take a look on the net (at least fishbase.org) under these names. Bob Fenner>
Thank You,
best regards !
