Overview

Available in the trade for the first time ever! You've read about this exciting new algae grazer from Tonga, heard rumors about, maybe even seen it come and go within hours on Diver's Den. . . now's your chance to be the first in your reef club to feature the Tongan Black Foxface in your showcase aquarium!

Differing from the Fiji Foxface (Siganus uspi), which has a distinctly bright yellow posterior, the NEW Tongan Black Foxface is almost entirely black except for lighter pectoral fins and posterior margin of the dorsal, anal, and caudal fins. The Tongan Black Foxface also has a white opercular stripe that appears composed of smaller interlocking wavy lines, versus the clearly spotted stripe on the Fiji Foxface. Also unusual for a foxface, the Tongan Black has been observed displaying fright coloration when stressed.

The Tongan Black Foxface may reside in a 125-gallon or larger aquarium. It is a very peaceful species except when housed with other rabbitfish. The Tongan Black Foxface may be housed with more aggressive fish. Its predators will tend to leave it alone because of its venomous dorsal spines. Rabbitfish are generally reef-safe if they are well fed. If not, it is possible for them to nip at and consume some species of LPS and soft corals.

The Tongan Black Foxface diet should consist of a variety of fresh vegetables, dried seaweed preparations, Spirulina Brine Shrimp, and enriched Mysis Shrimp.
