Maybe a juvi belly crawler? I'm not sure either.Pretty sure thats a pike cichlid and not a hoby. Not sure on the species though but they can be aggressive lil buggers and not all stay little.
That was my thought. At first it threw me off because as duanes pic shows baby belly crawlers have a kinda pointed nose but they do broaden over time and I think the fish in the op is just sickly and stuntedThink it is a very underfed crenicichla reticulata. The head looks so big because it is so skinny. Get to feeding that thing.
