The extensive range of ‘Cichlasoma’ istlanum has given origin to several geographic color forms of the fish, the one shown in the photographs I have to admit being not the most colorful variant but coming from one of the few areas I know where the water is clear enough to take underwater photographs, Rio Papagallo in the Guerrero State N.
