Geophagus abalios, possibly altifrons. Too hard to tell from your photographs, so I'm going purely from the third photo showing striped areas in the caudal patterning (although lateral spot and shape looks altifrons'ish) - give it a few months.
Can't believe people around here still ID Geophagus as "surinamensis", especially when they're 2" - every single thread about them ends up in a discussion about how they are basically non existent in the hobby, at least not from a mainstream perspective, and how in the US they're commonly mislabelled altifrons/abalios variants.
