Bicolor Blennies, or Ecsenius bicolor, are colorful fish that can be a great addition to your saltwater aquarium. Specifically, the Bicolor Blenny features a brown color on its front side, with a yellow-orange color toward the middle and tail end. They’re relatively easy to care for and can even help clean your tank by consuming algae that build up over time.

Is the Bicolor Blenny reef safe?

Bicolor Blennies are typically reef safe, but they may become a problem in reef tanks without the proper care. They’re herbivores that feed on algae and will ignore coral in most cases. However, crowding and underfeeding could make the Bicolor Blenny less coral-friendly.

Bicolor Blennies may start nipping at coral or other invertebrates, specifically large stony polyps (LSPs) and tridacnid clam mantles. They may also attack coral when foraging.

These risks make it important to look closely at your tank to determine whether your Bicolor Blenny is behaving peacefully among the coral. 

Bicolor Blenny food and diet

Bicolor Blennies are herbivores that can feed on a lot of vegetation. Typically, the Bicolor Blenny feeds on algae in the tank, making it a great cleanup fish. You can use a pipe or rubber band to lower algae into the tank when feeding your Blennies, which will help you avoid disturbing them.

In addition to algae, you can feed your Bicolor Blenny herbivorous meals, algae-based dry foods, garlic, and even frozen Mysis shrimp.

What other fish are the best tank mates for the Bicolor Blenny?

Bicolor Blennies tend to be content and healthy fish with the right tank mates. While a single Bicolor Blenny is great to have, they don’t often like sharing the tank with others of their kind. The exception to this is if you have a male and female—otherwise, stick with one.

They also don’t like to compete with other fish of similar or smaller sizes, meaning they’ll go after Gobies, Dartfish, and other Blennies. You should also avoid keeping larger fish unless the Blenny has plenty of space to hide in caves and coral.

If you’re looking for the ideal tank mates for your Bicolor Blenny, you’re better off going with the following:

  • Tangs
  • Chromis
  • Boxfish
  • Pufferfish
  • Damselfish
  • Butterflyfish

Bicolor Blenny FAQs

Do Bicolor Blennies jump?

Bicolor Blennies often jump from hole to hole within rocks in their surroundings. This means they may leap from the tank without the proper precautions.

Are Bicolor Blennies aggressive?

Generally, Bicolor Blennies are peaceful fish that won’t go after other fish or invertebrates. However, they have been known to get somewhat aggressive with certain fish, including Dartfish, Gobies, and other Blennies. They may also begin nipping at coral unless you feed them well and minimize stress in the tank.

Are Bicolor Blennies hardy?

While Bicolor Blennies are hardy, drip acclimation is still needed. You may need to use this method for around an hour if there’s enough of a difference between the tank and source water.
