i have 2 p.senegalus in the same tank and i have noticed both of them have bad damage to their front fins they move to swim(im not sure what theyre called) theres alot gone theres small pieces left they seem to be getting around fine. im not sure what caused this damage theyre in the tank with 4 african cichlids but i believe both of the bichirs have been attacking each other. will these fins heal completely? and what can i do to stop them from attacking each other?
