Very special thanks for the first photo of Black Foxface Rabbitfish to Cynthia A. DeLillo from Quality Marine, LOs Angeles, USA!!
The Black Foxface is another fish endemic to Tonga and is common only in the northernmost island group, Vavau. Because of the remote nature of this island these fish are even less commonly seen in the hobby, even though it is generally found in less than 45 feet of water or so. Juveniles of the species are usually found in schools; subadults are generally single and adults are either single or in pairs.
They are predominantly a grazing fish and attain a maximum size of 9". This somewhat larger max size means that this fish is much more commonly harvested as a food item than an aquarium inhabitant.
This is a "venomous" fish, where the venom is in its dorsal spines. The venom is very mild, but care should still be taken while handling.
