The Paeony Bulleye is a stunning addition to my 75-gallon tank. The deep red color and large eyes are truly impressive. It’s peaceful and doesn’t bother other fish. I’ve had it for six months and it’s thriving.

Beautiful fish with a unique look. I was cautious about keeping it in a reef tank, but it hasn’t damaged any corals. It’s active but not aggressive. Lighting really brings out the red coloration.
