Gold Midas Blenny is an ideal option for an aquarium with a reef. It's a stunning deep golden-yellow color with a blue-blue shadow under the chin and clear blue-rimmed eyes. While swimming, the movement they make is very eel-like. The blenny would prefer having a minimum tank that is 30 gallons or greater with plenty of rocks to rest. Sometimes the Midas Blenny can cause trouble to small planktivores and has been reported to attack gobies and fish. Tanks that are larger are more beneficial since some of the Midas's aggression traits appear to be related to a confined tank environment. Contrary to other blennies, this saltwater aquarium fish needs a substantial diet that includes small pieces of crustacean flesh Mysis, vitamin-rich brine shrimps, as well as frozen herbivorous dishes of blue-green algae and other algae based foods.
