Bicolor blennies being coral chompers? That's the first I've ever heard that before, mine grazes on algae and frozen but has never even looked at my corals... Where did you read that information? I guess if anything was hungry enough, any fish may try sampling sources of food but I've never heard of bicolors being nonreef safe.
Anyways, nice score on the ember, I was looking at one that was over $100, my guess is jl was selling it at a fraction of that price.
