The Harptail Blenny is an excellent candidate for a reef tank. It is a beautiful, deep golden-yellow with a shadow of green above the eye running under a jet-black dorsal fin.

This Harptail Blenny will appreciate a minimum tank of 30 gallons or larger with live rock. This species will graze on the numerous crustaceans found inside live rock. Harptail Blennies are passive fish rarely bothering other tankmates. This species has the ability to bite the inside of a predator’s mouth with its venomous fangs when ingested. The predator will then spit the small fish out of its mouth with no harm done to the blenny.

The Harptail Blenny should be fed a well balance diet of carnivorous foods along with a selection of foods designed for herbivores. These fish should be offered small quantities of food several times per day.
