The Bicolor Blenny has an elongated body with the anterior colored in dark purple and the posterior in yellow to orange. They have long straight cirri. These little fish have tons of personality and love to find a favorite 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 love to graze on algae throughout the aquarium and will often experience "pale patches" on their face and body when lights are first turned on. The Bicolor Blenny should not be mixed with other Blennies in small tanks. They are great for reef tanks and will accept most fish foods.
