Did you know fantastic help is an anagram of Planet Catfish? This forum is for those of you with pictures of your catfish who are looking for help identifying them. There are many here to help and a firm ID is the first step towards keeping your catfish in the best conditions.
Tough to tell for sure, but 204, 401, and 260 are all good candidates. I'm leaning towards 260, but that's a wild guess. I bet it's one of those three, however.
Looks like a male dwarf panaque of some sort, but not L204 (belly is different - tail filaments can be missing on 204's due to bad water or fighting), and probably not L104 panaque maccus (too black/white vs. brown/gold).
Might be missing tail due to fighting, Not sure. He is in with a larger royal pleco of some kind. Don't think he had the long tail fins when I got him but got them both at the same time. The tank is over filtered with weekly water changes so he isn't in bad water. Looks like the panaque but his white stripe seems thicker to me.
Could you take a picture of the teeths so we can see them clearly? A picture when the fish is in the aquarium so we can see his bodyshape more natural, I think it's a Hypancistrus species and not a Panaque but even if the last pictures is quite good it's hard to make any correct id.
The fish is for sure not L204.At that size the male L204 does not 'exhibit' odontodes and spines.It is very small in order to be a mature male Panaque L204....
As Janne said i also suspects Hypancistrus...
I have seen identical fish to the last Heiko Bleher's seminar in Athens....
Can't get a close up with my camera. Hope these help. Best I can do. I don't think he is going to get much bigger. Had hiim for 9 months and hasn't really grown anymore that I have noticed. Thank you again.
