Adam Taylor –
Easy to care for and fits well in my 30-gallon reef tank. It’s active but not overly aggressive. I’ve kept it for six months and it’s healthy and vibrant.
Elizabeth Churchill –
Good choice for a beginner reef tank. It doesn’t eat corals and stays calm most of the time. A bit territorial with smaller fish, but manageable.
Theresa Martin –
Arrived quickly and the fish was healthy. It’s a nice addition to my tank and has adapted well to the environment in a few weeks.
