I've had a Blue face angel in my 125 gallon for over a year now. Looks great a little aggressive but i can deal with that. My problem is he hasn't ate is in 6 days. Like i said looks great acts normal just stopped eating all of a sudden. Should i worry anyone have any idea what is going on here? Its a 125 gallon FOWLR tankmates are yellow tang, box puffer, copperband butterfly, flame angel and a foxface.
