I'm thinking of getting a Ctenopoma nebulosum to add to my 55g, but the only problem I forsee is my Ctenopoma acutirostre (Bubba) not liking the new addition. Has anyone ever added another ctenopoma to a tank where one has already established itself? Also the new one is about half the size of Bubba. Bubba used to chase cichlids I had in the tank but never hurt them. He is very peaceful towards my angels, plecos, and SA lungfish that are in the tank. Any experience keeping multiple ctenopomas would be greatly appreciated!!!
