placidochromis electra or placidochromis deep water hap. The second one could be a red fin borelyi but it is pretty dark. I'm surprised to hear you say he is killing everyone. I wanted to get one but dont need all of the destruction. Is he the biggest in the tank?
Ty for all the feedback. Yes the first one in my pictures has claimed a lemon jack and a beautiful OB peacock. Any resistance is met with death it seems like. I've seen them very aggressive in my LFS also. He is about the same size as a few of my others.
I'll most likely throw him into my 30g tank with three tiger barbs if he strikes again. That and I'm looking for a little bigger fish to keep the peace, some one to put the deep water in his place.
