Bought this rabbitfish for my 150-gallon reef tank. It’s very active and has been helping control algae without causing any issues with other fish. The yellow color is vibrant and it looks great in the tank. Only noticed the spines when it was startled, but it’s not aggressive otherwise. A solid addition to any reef setup.

It’s been in my tank for three months now and still shows great interest in grazing on algae. The black-and-white face pattern is very noticeable. I keep it in the mid to lower area with plenty of live rock. It’s not shy and moves around a lot, which is a good sign for a community tank.

The fish arrived healthy and has adapted well. I appreciate its algae-eating habits—it’s reduced the need for manual cleaning. It’s calm most of the time and only shows signs of alertness when approached. Very happy with the purchase.
