The rabbitfish is active and peaceful in my 120-gallon tank. It doesn’t bother the corals, though I keep an eye on it. Feeds well on algae wafers and small vegetables. Good choice for intermediate reef keepers.

Arrived healthy and has been thriving in my tank for three months. It’s not aggressive and stays near the lower levels. I noticed it occasionally brushes against a soft coral, so I’ve moved it slightly away.

Perfect for a balanced reef setup. The fish is calm and eats regularly. I appreciate the clear labeling and accurate size information. It’s a solid addition to my aquarium.
