Species Overview

Foxfaces and Rabbitfish are hardy marine fish, similar to tangs and surgeonfish. Most are some shade of yellow, with blue, silver or brown markings. They may be kept singly or in pairs in a home aquarium. They typically form pairs when they are around 4 inches long and the pairs are believed to last until one of the partners die. Different species of Foxface or Rabbitfish should not be mixed, but they can be housed with other members of their own species, especially when young. Older specimens form pairs in the wild and should ideally be given the same opportunity in the aquarium.

These fish are considered reef compatible with caution, because they are known to nip at some soft and hard coral polyps, especially if not fed well enough in the aquarium.

They are mostly herbivorous and feed on algae growing on rock and coral bases, but may turn to feeding on polyps if algae is scarce. They will not bother smaller fish and mobile invertebrates. In the aquarium, it is important to provide the fish with a varied plant and algae-based diet. Natural algae growth in the aquarium will be appreciated, allowing them to graze as they would on the reef.

Foxface and Rabbitfish can look blotched or discolored when stressed or frightened. They may also appear with these strange coloration late at night or early in the morning when the light in the tank changes. The blotches help them to blend with rocks while they rest at night. When the fish feels at ease the color should return to normal.

Venomous Animal Precautions

The venomous spines of Rabbitfish and Foxfaces are used exclusively for defense. The potency of the venom varies by species, and effects can range from a strong irritation to very painful or even life-threatening reaction. Most stings in the aquarium happen accidentally, a result of the aquarist making contact with the spines while maintaining the tank. Feeding any animals in the tank by hand can increase the risk of being stung. As a precaution, we recommend being aware of the basic first aid required in the event of a sting, and secure a tank including venomous animals from small children.Always be aware of where your Rabbitfish is when working in your aquarium, and seek medical attention immediately if a sting should occur.

We always suggest that you do further research before adding a new pet to your tank. What we have provided for you are guidelines and suggestions. If you have any further questions or concerns, please contact our fish room at 717-299-5691 ext. 1213 or
