Bicolor Blenny

Ecsenius bicolor, commonly known as the Flame-Tail Blenny or Bicolor Blenny, is a fascinating fish found in the waters surrounding Fiji, Sri Lanka, the Maldives, and Indonesia. Divers exploring exotic Indo-Pacific lagoons and reefs often encounter this species. Here are some interesting details about the Bicolor Blenny:

• Appearance: The Bicolor Blenny has a unique body with a blue top half and an orange-yellow bottom half. Its single ultra-long dorsal fin and large, protruding eyes give it an almost alien-like appearance. During breeding, males undergo dramatic color changes, turning deeper blue, while females have a duller orange “flame” on their tails.
• Diet: These “worker bees” of the seas help keep tanks clean by busily stripping algae from corals and rocks using their rows of tiny, comb-like teeth. Tank owners appreciate their algae-eating abilities.
• Size: Bicolor Blennies grow to a maximum length of 11 centimeters (4.3 inches).
• Lifespan: While not known for an exceptionally long lifespan, these blennies can still provide endless awe for aquarium enthusiasts.

If you’re considering adding a Bicolor Blenny to your tank, make sure to provide the right tank size, water parameters, and suitable tank mates.
