Whatever he is he's by far my favorite fish even though I'm pretty new at fish keeping. He is a stunning color of blue and when I shine my flashlight into the tank to find some that are hiding he really looks great whn light is bouncing off of him! Such a beautiful fish but not much of an eater right now though and he's the biggest and actually meanest fish in the tank right now. He will hardly even touch cichlid sticks, pellets, or flakes but he does seem to like to eat neon tetras here and there. I use them instead of rosy reds bc they just always look and seem healthier.
