Hi, I found this site when I was looking up compatablity on black ghost knife fish. Does anybody know what would be the best tank mates for it? I have a 4 1/2" one that I just moved into a 50g with some feader guppies everywhere. Iv'e had him since he was only 2 1/2" long. I want something else besides just him in there. Anybody have any advice?
