Bicolour Blenny

This is a Bicolour Blenny. Originially from the Indo-Pascific, they're now a fish tank favourite.
They're easily stressed out and will attack when threatened. For this reason, Bicolour Blennys are jerks.
These little demons just cant wait to take a nice fat chunk outta one of your digits. They also like meaty foods such as shrimp and dried bloodworms.

They're known to omnom on algae as well. When they clean the glass of the tank they leave behind little kiss marks.
