I have a Ctenopoma acutirostre that is now 3 yrs old and about 6". A male that shares the tank with a 12" polyopterus. He has now developed a growth on his lip that looks like a massive spot, any ideas what this could be?
Heres my old one-really regret getting rid of it a while ago. They always remind me of mini freshwater groupers and are really cool fish to keep. don't see them for sale here that often and when I do they're always too small to go in my tank.
