Nicola Carr –
I’ve had this female Pseudanthias Bimaculatus for six months in a 100-gallon reef tank. She’s active and colorful, and has not shown aggressive behavior toward other fish. The tank is stable and the coral community remains undisturbed. Only recommend for experienced reef keepers.
Michelle Metcalfe –
She’s a striking addition to my tank. I noticed she’s more active during the day and tends to stay near the back wall. I’ve kept her with a few peaceful tangs and she coexists well. Requires a large tank and stable water conditions.

The fish arrived healthy and looks vibrant. I’m still adjusting to her behavior since she’s semi-aggressive. I’ve added more hiding spots and increased water flow. Will monitor for any aggression over the next few months.
