The Bicolor Blenny, Ecsenius bicolor, has a bisecting color pattern with the front half being a blue to pale brown color and the back half is orange/yellow. They are hardy and can be housed with other peaceful fish in a reef tank setting, but may become territorial towards other blennies, gobies or dartfish in smaller tanks.
This blenny will stay mainly towards the bottom of the tank, searching for algae to graze on in between meals. Diet should include a variety of spirulina, marine algae, and seaweed and algae based foods 2-3 times daily.
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.
