Looks alot like a Vieja (paratheraps) species to me.
Well howdy lol
Alex, try googling imagaes of Veija too as Minxfishy suggests, its easier when you have the fish in front of you rather than us guessing from a photo, I must admit Veija never came to my mind as I was sidetracked on you saying it was a texas and I get sidetracked so easily lol
