It's an Amphilophus species. Barred midas-type of some sort. There are about 13-14 closely related species that are not easily distinguishable. The 2 most common in the trade are the Midas and Red Devil, and the common aqaurium strain is likely a mix of the two. Types that are found in murky water undergo a "peeling" process and change from barred to orange/yellow. But many, or most of these kinds remain barred and do not "peel".
