Easy to set up and very peaceful in my 75-gallon tank. I’ve kept it for six months and it hasn’t shown any aggression. The fish is active but not too demanding. Only need to watch for coral interactions, which is manageable with regular checks.
Maria Payne –
Grew nicely in my tank over three months. It’s calm and doesn’t chase other fish. I noticed it occasionally nips at soft corals, so I’ve moved them slightly away. Overall, a good choice for a beginner reef tank.
Kevin Murray –
Perfect for a small reef setup. The fish is healthy, stays in one area, and doesn’t stress other inhabitants. I appreciate the beginner-friendly care level and the clear size guidance.
