After looking around, I came up with these. These are from the ID thread in the sticky section.
This one is a Cichla monoculus "Enviria Lake".
This one is Cichla monoculus "Mazan"
As a pbass ages, the solid spots and stripes break up and form a blended pattern. Make note of where the blended paterns are and their shape when comparing adults to juvies.
Notice these traits on yours and those in the picture:
1. a)The side spots extend with a lighter band over the top of the fish.
1. b)The side spots end just below the lateral line.
2. The horizontal line, both at the tail and the faded continuation down the lateral line.
3. The eyes are not red.
Your fish is certainly a Cichla Monoculus (mono.) but which type and which lake it originated in will have to wait until it grows some more. Still, a very nice fish.
