Bi-color Blenny: Reef safe?
I added a bi-color blenny to my community a few days ago...seemed fine and left the other fish alone, scooting around the rock work. But today, I noticed it would "pick" at my brain coral and fans. I wasn't sure if it was picking gunk off the coral, or actually picking at the meat. I didn't notice any tear/bite marks, or much of a reaction from the brain (such as closing up or shriveling).
1- is this normal behavior?
2- is it really picking at the coral?
I feed a combo of flakes and mysis shrimp every other day. I always see it go after food (can't really tell if it eats or spits any back out though).
