More info on the Harptail --- I love mine, real personality
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.
Like most blennies, the Harptail Blenny requires a meaty diet including finely chopped crustacean flesh, mysid and vitamin-enriched brine shrimp, along with frozen carnivore preparations. These fish should be offered small quantities of food several times per day.
