Midas Blenny

The Midas Blenny (Ecsenius midas), also known as the Golden Blenny or Sunburst Blenny, originates from the Indo-Pacific region, favoring rocky or coral-rich habitats. With a size reaching up to 6 inches and a lifespan of several years, it boasts an elongated body transitioning from light orange to golden yellow, accentuated by sapphire blue eyes. This herbivorous species requires a varied diet of marine algae sheets, spirulina-based pellets, and occasional fresh or frozen vegetables.

To thrive, the Midas Blenny requires a well-established aquarium with plenty of live rock for hiding spots and algae growth, along with adequate lighting. The Midas Blenny adds vibrancy and charm to saltwater marine aquariums, becoming a focal point of admiration with proper care and a suitable environment.

I wrote earlier that the SE Asia Midas looked different fromthe 1 pictured of the African variety. I was wrong. It looked different initially but looks just like the African counterpart. Very cute and loads of personality.

Love this fish! It was dark colored for 4-5 days and is now getting more yellow each day.
