The Bicolor Blenny, Ecsenius bicolor, also known as the Two Colored Blenny, is named for its two-colored body. The front half of the blenny is a purple/brown color and the back half is often an orange/yellow color.
This Blenny is an excellent reef dweller and makes a great addition to almost any tank. It is an active, hardy, and personable fish. Their funny swimming style makes it actually look like they are hopping across the bottom of the tank.
While generally friendly, the Bicolor Blenny can get semi-aggressive with similar-looking species. They will require a tank of at least 30 gallons with plenty of live rock hiding places and a tightly sealed lid to prevent escapes. They can also be beneficial tank members by helping dispose of algal growths and other natural vegetation found around the tank as they are voracious herbivores.
These fish are really neat because their personalities really shine. Along with their "hopping" swimming motion, the Bicolor Blenny will perch atop rocks, poke their heads out to keep watch, and are always really active around the tank.
I absolutely love the Bicolor Blenny. They perch in holes in the live rock. If you get them at the right angle their face seems to have spots that light up with the antenaes and mouth. Gives it a very cool look. Mine seems to have found a home under my Zoas and actually protects the Zoas when other fish or crabs get near.
Very healthy fish, eating well.
Love these little fish. They have so much personality, they are very feisty little fish. Love how they stick up for themselves. Once they have established their territory they defend it to the max. No they are not aggressive, just stick up for themselves
The blenny was in great shape when he showed up and Ive had him for 6 months. But I thought I was killing off my 2 Acan colonies but after a few days of observation my blenny was eating them, kinda look like what a lawnmower blenny does to algee. Moved him to my sons FOT. There not always reef safe.
