The Golden Midas Blenny is an African color variation of the regular Midas Blenny (Ecsenius midas, also known as the Persian Blenny). This form has an even more brilliant golden color than other Midas Blennies and is fairly uncommon.

Midas Blennies are peaceful but generally shy fish. They may become more active and hover in the water column when comfortable, but they spend much of their time peering out of holes or caves. They will not bother most other fish but occasionally pick at very similar gobies, blennies, firefish or dartfish. This species does not eat much algae, feeding primarily on zooplankton.

Many different species and varieties of blennies enter the aquarium trade regularly. Some of the more commonly encountered genuses are Atrosalarias (the Sailfin Blennies), Blenniella (Rockskipper or Combtooth Blennies), Ecsenius (often small and flat-faced), Meiacanthus (the notorious fangtooth blennies), and Salarias (the popular algae-eating Lawnmower Blennies). Many blennies may eat some algae growing in the aquarium like the nuisance hair algae, or ornamental macroalgae like Caulerpa. Blennies will also accept many other types of food like pellets, frozen formulas, brine shrimp and others.

Blennies can be kept with most other community tankmates like damsels, clownfish and angels but they may become territorial with time and will defend against trespassers. Blennies typically do not tolerate others of the same species except in very large aquariums with enough territory to accommodate their need for space. They are safe for reef aquariums and will not harm most invertebrates, with the possible exception of small crustaceans like Sexy Shrimp. They spend most of the time on or around the bottom, or perching in the rockwork of the aquarium.
