This blenny will appreciate a minimum tank of 30 gallons or larger with numerous rocks on which to perch. Sometimes, the Midas Blenny will vex small planktivores and has been known to nip at firefish and gobies. Larger tanks are advantageous as many of the Midas Blenny's aggressive behavior traits seem to relate to a confining tank situation.
Unlike most blennies, the Midas Blenny requires a meaty diet including finely chopped crustacean flesh, mysis and vitamin-enriched brine shrimp, along with frozen herbivorous preparations, micro and blue-green algae.
