Bicolor Blenny Diet & Nutrition: Omnivorous - a voracious eater that will eat a variety of foods including algae, flakes, pellets, frozen mysis shrimp, and frozen brine shimp. While the bicolor blenny will happily eat meaty foods, it must have some vegetable matter in its diet. If there is not enough algae in the tank, dried algae or seaweed should be added to ensure health.

Bicolor Blenny Description: The bicolor blenny is one of the more personable saltwater aquarium fish available. With their unique mannerisms and a toad-like face, they often capture the interest of their owners and visitors alike. This is typically a hardy species and does well in an established aquarium with algae growth.

The bicolor blenny is an active digger and will move sand, shells and small rocks to fit its needs. Rockwork should be well supported to ensure that rocks do not tumble down as a result of the blenny digging in and around its cave. While most individuals seem to be reef safe, some have been known to nip at corals or clams. A well fed blenny is less likely to disturb other inhabitants.

Tank Mate Compatibility: A good community fish, but may become territorial with other similarly colored fish and gobies/blennies of any color.

Determining Bicolor Blenny Sex: No reliable way to determine visually.
