The front half of the Bicolor Blenny is usually dark purple-grey, and the rear is orange-yellow. During spawning, the male turns reddish with white bars and the female turns light brown and yellow-orange. After spawning the male becomes dark blue with light patches on each side of the body.



The diet of the Bicolor Blenny should include vegetable matter, including frozen and dried foods containing marine and blue-green algae. It will also feed on (and help control) algae growing in the aquarium.



The Bicolour Blenny is an egg-laying species. The eggs are adhesive and can be found on or near the bottom.

Blennies can be kept with most other community tankmates like damsels, clownfish and angels but they may become territorial with time and will defend against trespassers. Blennies typically do not tolerate others of the same species except in very large aquariums with enough territory to accommodate their need for space. They are safe for reef aquariums and will not harm most invertebrates, with the possible exception of small crustaceans like Sexy Shrimp.



They spend most of the time on or around the bottom, or perching in the rockwork of the aquarium.
