I have a 7" black spotted eel (Mastacembelus dayi) and a 12" tiger bichir (Polypterus endlicheri). I'm wondering if I could put a black wolf fish (Hoplias curupira) with them? The Bichir I think would be fine but I'd rather not have my eel eaten or beat up by the wolf fish. I have a grow-out tank I could put him in temporarily but long term they'd have to go in the big tank together. Does anyone know if this would or wouldn't work?
