Also known as the Foxface, Common Foxface or Black-face Rabbitfish, this Western Pacific species is popular in larger marine aquariums for its hardy nature, striking colour and strong appetite for nuisance algae.

Carolyn Duncan –
Added a Foxface Rabbitfish to my 120-gallon reef tank. It’s active and eats algae efficiently without bothering the corals. The coloration is vibrant and it looks great in the tank. Only needs a bit of space to swim freely.
Harry Rutherford –
This fish is a great addition to a mature marine setup. It’s peaceful and helps keep algae under control. I feed it daily with algae wafers and blanched vegetables. It’s easy to care for once the tank is established.

The fish arrived healthy and has been thriving in my tank for three months. Its white face and black mask stand out well. It’s not aggressive and doesn’t stress other fish. A reliable algae eater.
