Nice little female Crenicichla sp. 'belly crawler'
Very cool pikes. They get around 8 to 10" when mature, and basically what you see is what you get. Since you got a female she will get some orange/red on her side, and some in the dorsal as well.
Pretty much one of the easiest of the Crenicichla to keep. Not very demanding, quick to be trained onto prepared foods, and pretty interactive.
