Bicolor Blenny

The Bicolor Blenny (Ecsenius bicolor) is a popular species among saltwater aquarium hobbyists. They are small, growing up to 3 inches in length, and are known for their distinct two-tone coloration. They are relatively hardy and easy to care for, making them a great choice for beginner hobbyists.

Bicolor Blennies are omnivores, and in the wild, they feed on algae and small crustaceans. In captivity, they should be fed a varied diet that includes both meaty and plant-based foods. They will readily accept commercial flakes or pellets, as well as live or frozen brine shrimp, mysis shrimp, and other small crustaceans.

There are no external differences between male and female Bicolor Blennies.

Breeding Bicolor Blennies in captivity is difficult and rare. In the wild, they are known to spawn in caves or crevices in rocky areas. If you are interested in breeding them, it is recommended to provide them with plenty of hiding places and live rock in their aquarium.

Like most saltwater aquarium fish, Bicolor Blennies are susceptible to common diseases such as ich, fin rot, and marine velvet. Proper water quality, regular tank maintenance, and a balanced diet can help prevent these diseases.

Bicolor Blennies are native to the Western Pacific Ocean, specifically the waters around Indonesia and the Philippines.

Bicolor Blennies are generally considered peaceful and can be kept with other peaceful fish. However, they may become territorial towards other Blennies or similar-looking species. They are not known to be venomous.

It is important to properly acclimate Bicolor Blennies to their new environment before introducing them to the aquarium. This can be done by slowly adding small amounts of water from the aquarium to their shipping bag over a period of time, gradually increasing the salinity and temperature to match that of the aquarium.
