That is a better shot, but it's still a tough one. Am I even right with Vieja for a genus? It has the colouration of plenty of Vieja fry I have seen, but the face doesn't look quite right.
The other Vieja and Paratheraps I own and have owned over the years never exhibited this coloration. Generally you will see some sort of pattern or distinct seperation of colors. The fish above will ultimately change completely when adult.
