Ava Dyer –
Easy to care for and very peaceful in the tank. It doesn’t bother other fish or corals. Grew to about 4 inches and looks great in a 50-gallon reef setup. Perfect for beginners.
Jasmine Morrison –
Arrived healthy and stayed active. No aggression observed. Fits well in a reef tank with other species. Slightly smaller than expected, but still looks vibrant.
Joan Berry –
Great addition to my beginner reef. It’s calm, doesn’t eat corals, and has a unique appearance. Grew to 3.5 inches in a few months. Very satisfied with the purchase.
