I believe It is a barred midas, Amphilophus citrinellum. The body shape and the shape of it;s head is consistent with the species. It's not a Lyonsi or a Trimac. The body is wrong on the former and the latter as pointed out...would have some large or small pearling. I can see how it would be mistaken for Lyonsi based on the picture I posted on the other thread.
Folks are too quick to call out hybrid. And how people can volunteer the "mix" with any accuracy has always been beyond me. I've been looking at CA cichlids for over thirty years and I couldn't do it.
What color is the fish's eye? Just curious.
