Venomous spines on its back

The foxface rabbitfish is a tropical saltwater fish, mainly inhabiting shallow waters. It prefers to spend its time in rocky coral reefs, lagoons and transitional waters between lagoon and open sea. The foxface rabbitfish has a friendly appearance and gets its name from its gentle, rabbit-like face. But be careful! The foxface rabbitfish has venomous spines in the fin rays on its back that protect it from predators. If a human is stung, it can cause a lot of pain, as well as breathing and heart problems.

Changes colour

The foxface rabbitfish is active and fearless. It has the ability to change its colour to a darker one that is adapted to the surroundings. This happens at night when it is dark or when the fish is stressed. The foxface rabbitfish is territorial, and usually swims alone or in pairs. Males and females form pairs when they are very young. After mating, they spread a large number of fertilised eggs in the water. While developing, the eggs float in a protected environment among corals and plankton.
