Keeping Bicolor Blenny (Ecsenius bicolor) in an Aquarium

The Bicolor Blenny, also known as the Two-color Blenny, is a popular and easy-to-care-for species that can make a great addition to a reef or community aquarium. Here are some things to keep in mind when keeping Bicolor Blennies:

Appearance

Bicolor Blennies have a unique and striking appearance. They have a slender body with a pointed snout and a single dorsal fin that runs the length of their body. Their base color is a deep blue-black, and they have a bright yellow stripe running horizontally down their body, which is where they get their name. They can grow up to 4 inches in length.

Behavior

Bicolor Blennies are generally peaceful and can be kept with other non-aggressive fish. They are known for their entertaining behavior and can often be seen perching on rocks or coral, darting in and out of crevices. They are also known for their jumping ability, so it’s important to have a tightly-fitting lid on the aquarium.

Diet

Bicolor Blennies are omnivores and will eat a variety of foods, including algae, plankton, and small crustaceans. In the aquarium, they should be offered a varied diet that includes both meaty and vegetable-based foods. They will also graze on algae growing in the aquarium.

Tank Requirements

Bicolor Blennies are hardy and adaptable fish that can thrive in a range of aquarium conditions. They prefer a well-oxygenated aquarium with plenty of hiding places, such as rocks, coral, or PVC pipe. They also appreciate a sandy substrate that they can burrow in. They are not picky about water parameters, but the water should be kept clean and well-maintained.

Coolest Stuff

• Bicolor Blennies are known for their unique swimming style, which involves a series of quick, darting movements.
• They are one of the few blenny species that can be kept in a reef aquarium, as they are not known to nip at corals or other invertebrates.
• They have been known to change color depending on their mood or environment, with some individuals exhibiting a brighter or duller yellow stripe.
• Bicolor Blennies have a symbiotic relationship with pistol shrimp, which provide them with a burrow to hide in and warn them of predators.
