And another.


The Bicolor Blenny has an elongated body with the anterior coloured in dark purple/brown and the posterior in yellow to orange. They will usually have tiny appendages on the top of their heads called "cirri". These fish have tons of personality and love to find a favourite spot in the aquarium to call home. They will often use rock crevices, caves, and empty barnacles to hide their body and allow their head to poke out to keep an eye on what's going on. They sleep in a favourite hole each night. They love to graze on algae throughout the aquarium and on the sand bed. They will often experience pale patches on their face and body when stressed and when lights are first turned on.

They are a great addition to reef tanks and will accept most fish foods.
