Bought a female bimaculatus for my 100-gallon reef tank. She’s been active and healthy after three months. The initial size was very small, as described. She’s not overly aggressive but does defend her space. Good for experienced reef keepers.

The fish arrived healthy and small, as expected. She’s been in the tank for six months now and has grown steadily. I’ve had to be careful with tankmates, but she’s not causing issues with the coral.

Perfect fit for my expert-level reef setup. The female is calm and colorful. I appreciate the clear size description—she’s still under 1 inch now, which matches the listing. Great choice for a reef-safe, semi-aggressive species.
