I added this fish to my 80-gallon reef tank after researching compatible species. It has been thriving for six months and is very active without causing any issues with the corals. The fish is peaceful and maintains a clean appearance. Great choice for intermediate reef keepers.

The fish arrived healthy and has adapted well to the tank. It swims gracefully and doesn’t bother other fish. I appreciate that it’s reef-safe and not aggressive. A solid addition to a balanced marine ecosystem.
