Revillagigedo barnacle blenny (Acanthemblemaria mangognatha)Blennies are not a large growing species and can therefore be kept in medium to large sized aquariums. They are generally peaceful towards other fish and make excellent additions to community aquariums. Blennies can however be territorial and aggressive to members of their own species and it is recommended that only a single fish of a specific species be kept in an aquarium. Although blennies are often kept in reef aquariums, they do like to nibble on coral and live rock.

Blennies are a fairly reclusive species and enjoy aquariums with a great deal of rock cover and hiding places. They also enjoy burrowing and digging and should be provided with a soft sand substrate. It is also important that the rock fixtures in the aquarium be firmly fixed to prevent them from toppling because of the fish’s burrowing activities.

Blennies are gregarious feeders and will accept most types of live, frozen and dried foods. It is advisable to feed blennies a varied diet. If not adequately fed, blennies are known to attack and devour small invertebrates in the aquariums.
