I've decided to go with a belly crawler pike. I've read they only grow to about 6 inches. I'm just having trouble finding them. I would like to put one other fish in there with it though. Thanks for the ideas.
Something from Lake Tanganyikan. They are sooooo cool. My dad just bought me a book (paid way too much) and it has every cichlid species in the entire lake. Truly fascinating. Yeah, check 'em out. Definitely. I can give some examples after I've looked into it.
