Bicolor Blenny Question

[dstipple]

I picked up a little bicolor blenny about three weeks ago. He's about 2.5" so I'm assuming he's still a juvenile. I noticed hip pecking at a Christmas favia I have about a week and a half ago and now it looks like it is almost melting away into the rock. I know its because he's been nipping at it and today I noticed my brain coral has some pale spots on it and as I'm inspecting it the bicolor comes over and nips at it!

Has anyone else had this experience with a bicolor? If he keeps this up it's back to the LFS for sure!

As I recall, bicolor blennies are not reef safe. I've seen quite a few threads about them going after corals, especially SPS. I'd start trying to catch him now before he moves onto the next piece.
