I’ve had this fish for three months now and it’s been very calm and active. It hides in the rockwork at first but now swims freely. Feeds well on brine shrimp and mysis. Great addition to my 120-liter tank.

The fish looks beautiful with its orange spots. It’s not aggressive and stays in the back of the tank. I give it a few weeks to adjust, and it settles in well. Feeds easily on frozen foods.

A peaceful and elegant fish. It’s been a highlight in my saltwater setup. The coloration is vibrant and it doesn’t stress other fish. Easy to care for once you provide enough open space and hiding spots.
