The Blackline Blenny is also known as the Blackline Fangblenny, and is bred in captivity in the USA. All blennies in the Meicanthus genus possess a venomous bite which is used as a defense in the event of being taken in by larger fish. When they bite the inside of the fish's mouth they are then spit out and are spared the loss of their lives. The fish are green and yellow in color and have a number of black marks that are lateral to the fish. The non-venomous Red Sea Mimic Blenny (Ecsenius gravieri) has evolved to mimic the appearance of this species. This aids in the survival of the species because predatory fish often do not bother them. This is why the Blackline Blenny is a peaceful fish and makes a stunning feature in any community aquarium. Usually found in crevices and rocks on the bottom of their habitat the Blackline Blenny requires an aquarium minimum of 10 gallons and scattered rocks for perching and hiding. They are usually peaceful in the wild and are considered to be reef-safe.   Diet of the Black-Lined Blenny needs to include meaty items like vitamin enriched brine and mysis shrimp, chopped pieces of shrimp and fish, and high quality flake food.   Approximate Size of Purchase Small 1 1/2" up to 2 1/2" Medium 1 1/2" up to 2 1/2"
