My best friend got this pike as a columbian pike but we are not sure what exactly it is. Its about 4" and just ate thats why his belly is big. Any ideas? It does have a spot behind its pectoral fins and some kind of patterning down its flanks as well as the lines on its head extend to its bottom lips

Crenicichla saxatilis?

thats a Sveni, pretty cool pike doesn't get big maxs out around 7''-8'' males can get to 9''-10'' but that would take a long time. Mines a total pig eats pretty much anything. It took a while but i was able to get him to eat cichlid gold pellets
