Bicolor Blenny (Ecsenius bicolor)

Description:

Behavior: The Bicolor Blenny is a peaceful and active species known for its entertaining and inquisitive nature. These fish are great for controlling algae in the aquarium, as they constantly graze on the rock surfaces. They are generally non-aggressive but may show territorial behavior towards other blennies or similar-looking fish.

Color: The Bicolor Blenny is aptly named for its striking coloration, with the front half of its body a rich, dark brown to black, and the rear half a vibrant yellow to orange. This distinctive two-tone appearance makes it a visually appealing addition to any marine aquarium.

Diet: Bicolor Blennies are herbivores that thrive on a diet primarily composed of algae. In captivity, they should be provided with plenty of live rock to graze on, supplemented with high-quality marine algae flakes, pellets, and frozen foods like spirulina and mysis shrimp. Providing a varied diet helps maintain their health and vibrant coloration.

Tankmates: Bicolor Blennies are generally peaceful and can be kept with a variety of other non-aggressive marine species. Suitable tankmates include clownfish, gobies, wrasses, and other small, peaceful fish. Avoid housing them with overly aggressive species or other blennies to prevent territorial disputes.

Reef Aquarium Compatibility: Bicolor Blennies are reef-safe and do not harm corals or invertebrates. Their constant grazing helps control algae growth, making them a beneficial addition to reef aquariums.

Max Size: Bicolor Blennies typically grow to about 4 inches (10 cm) in length. They can be kept in smaller aquariums, with a minimum recommended aquarium size of 10-20 gallons to provide adequate space for grazing and exploration.

Origin: Bicolor Blennies are commonly found in the Indo-Pacific region, including the waters around the Philippines, Indonesia, and the Great Barrier Reef.

Sexual Dimorphism: Bicolor Blennies do not exhibit significant sexual dimorphism, making it difficult to distinguish males from females based solely on appearance.
