Yellow Tail Midas Blenny (Escenius lividanalis) - is a beautiful, deep golden-yellow with a shadow of blue under the chin and bright, blue-rimmed eyes. When swimming, the motion they use is very eel-like. 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.
