November 11, 2010 : Tube Blenny

Tube Blenny

The barnacle blenny, Acanthemblemaria spinosa, also known as the tube blenny or spinyhead blenny, is a member of the blenny family native to the Pacific ocean. It has a mottled black, white and red coloration over the entire body, which is rather elongated. As with most blennies, the head of this animal has small hair-like appendages over the eyes, which are large and red. It ranges in size from 0.75 inches (19 mm) to 1.5 inches (38 mm) in length.

A. spinosa prefers to inhabit the empty shells of barnacles, hence their name, but will also live in rock and coral crevices. They are opportunistic feeders, preferring to quickly dart out and retrieve food bits from the water column, as opposed to engaging in active foraging and hunting behavior. They eat small crustaceans and other

In the home aquarium, they are entertaining and only require moderate care. They are reef safe.
