Jack Rees –
Bought this for my 150-gallon reef tank. It’s active and curious, and has not shown aggression toward other fish. The size is within the expected range. Good for intermediate reef keepers who want a unique, hardy species.

The fish arrived healthy and has been adjusting well. It’s not overly aggressive, but does defend its space. Needs a large tank, which I already have. Satisfactory for the price and species.
