Added this rabbitfish to my 120-liter reef tank last month. It’s very active and keeps the algae under control without disturbing the corals. The coloration is vibrant and it looks great in the display. Easy to care for and peaceful in the group.

Perfect addition to a mixed reef setup. The single black spot is very noticeable and adds a unique touch. It doesn’t eat anything else and focuses only on algae. Very satisfied with the purchase.

The fish is healthy and active. It’s not aggressive and doesn’t interfere with other inhabitants. A little shy at first but settles in quickly. Would recommend for reef tanks with algae issues.
