The Bicolor Blenny is aptly named due to its striking pattern of half yellow and half brownish purple. They are mainly found in the Indian and Pacific Oceans, and inhabit reef and lagoons, near corals or rocky rubble. The Bicolor Blenny belong to the family Blenniidae, the combtooth blennies. They are a popular aquarium fish and are considered quite hardy. The Bicolor Blenny can get along well with other tank inhabitants but often they can be aggressive to similar looking fish or same species fish. We recommend you to keep them in a closed aquarium as they are very good at jumping and can come out easily out of the aquarium. It is advisable to keep them well fed with marine and blue green algae either in fresh, frozen and freeze dried. The Bicolor Blenny is an egg-laying species, and their eggs are adhesive and are found nearly at the bottom. They can only swim a short distance, and rather than swimming it looks they are hopping. The presence of a few live rocks allow them to perch on as well as hide in and around. The Bicolor Blenny fish are mostly reef safe and bottom dwelling algae eaters. Avoid having more than one blenny in tanks smaller than 50 gallons as they will be territorial and fight. There is no distinctive feature to differentiate males from females. The Bicolor Blenny fishes are an excellent and easy to keep community specie. They will spend most of the time resting on the aquarium rockwork.
