Brandon,
The picture provided still is not clear enough to make a definite determination. I do know that they did have spectibilis cast offs from tparker in the store at one point. If the fish is south American I think you can throw out the possibility of it being a hybrid. Only one confirmed case of hybridization that I know of and it was with a convict and a convict like fish who's name is escaping me at the moment.
It does have umbee like barring IMO and an umbee like body shape.
Let it grow..
