i agreehmm never seen one like that. looks like a blue acara to me. not sure though. :welcome: to AC to!
I have to agree with the Uaru. I saw the picture and that was the first thing to jump to mind.Triangle Cichlid, Uaru Amphiacanthoides. Wrong head shape and markings for a blue acara. But I'm no expert, I just have a big fat book in my hands... Anybody else?
