You can get some black belts that don´t have the black belt itself, but I´m not sure what that fish is, I thought maybe Zonatus but after looking at pictures im not entirely sure.
The name of the fish would be "Vieja ******" so if you type in Vieja Cichlid, or research the different types of Vieja species then you might be able to find an ID for yourself? either that or just wait for someone to chime in. I know how hard it can be to identify Vieja, I had one years ago that I only got an ID on 2 years after I already sold it!
