Jasmine Bailey –
Easy to care for and very active in the tank. It doesn’t bother other fish and stays in the rock crevices. Perfect for a small reef setup. Has been in my 24-gallon tank for three months and still looks vibrant.
Lily North –
Arrived healthy and quickly adapted to the tank. It’s peaceful and doesn’t chase other fish. Only downside is it prefers shaded areas, but that’s not a big issue.
Isaac Hudson –
Great addition to my reef tank. The color change between light and dark is noticeable. It’s active during the day and hides at night. Very satisfied with the purchase.
