Bicolor Blenny

Found singly, often in abandoned burrows and worm tubes, amongst mixed corals, over clear water lagoons and seaward reefs, rich in algae growth. Colours vary from two colours to white bellied, with dark stripe on side and arched line behind and below the eye.
They feed on algae, from dead coral bases.

Combtooth Blennies are the largest family of blennies, found in both tropical and subtropical waters and freshwater habitats, as the name suggests they have comb like teeth lining their jaws, well suited for scraping food off hard surfaces!
Reef and rock blennies are usually territorial and have their own areas of rock pools which they skip and jump over, scraping algae from the surface of dead corals. Some male blennies have small harems of arguing females.
Males and females often have different colouring and features.
