In a few months I’ll be moving my belly crawler pike to a 55. He’s about 7”. He’ll most likely take the bottom of one half of the tank for his territory. He gets along fine with fish that stay up in the water column and that stay out of his territory. His territory has always been pretty small and limited to about 4” from the bottom but he guards it aggressively He will eat anything that is less than half his size, so I’m considering another mid sized cichlid but any other ideas would be appreciated. I like oddball type fish
