Yellow Tail Black Blenny (South Pacific)

Blennies are diminutive fish typically with elongated bodies, and as such we do not recommend any aggressive or large-mouthed fish to be kept with them; this includes all groupers, snappers, sweetlips, soapfish, lionfish, eels, goatfish, anglers/frogfish, leaf fish, and any other fish who may eat them.

The Yellow Tail Black blenny is an uncommon fish with striking coloration. Its other common name is the Black Comb tooth blenny, however the specimens we receive are black only on their front half. The rear half of the fish is bright sulphur yellow which makes an impressive contrast. Males and females are visually identical; however males may grow larger. It grows up to 4 inches.

The Yellow Tail Black blenny spends most of its time perched on top of or in rocks with its head sticking out, always alert and watching its environment. It is typically reef safe, preferring to graze live algae off the rocks.

Diet should include plenty of marine algae and Spirulina, frozen Mysis shrimp, and other high quality meaty items. It is preferable to feed more than once a day. We recommend an aquarium of at least 30 gallons or larger. Live algae is an important source of food, and should be growing in the aquarium before the blenny is introduced. Algae grazing blennies may be especially aggressive towards similar species, and are best kept one per tank.
