Agree with the above. Eupterus with badly and chronically damaged finnage. Google image Synodontis eupterus and you will see for yourself. Or visit Planet Catfish, ScotCat, etc. They have a gorgeous dorsal.
I'm glad mine isn't too bad. From what I can see. He usually hides behind the driftwood all day. I have noticed that my smaller bichirs tail is kind of split now. Idk what the cause is though.
