Hmmm, I think you mean a Lawnmower Blenny and I read somewhere that it actually is an omnivore after I freaked out when I saw it eat meat. They seemed to still state herbivore on the sites I just checked but mine eats a lot more. He will eat anything including shrimp,silversides,clam,flake,nori,spiriluna,brine, etc. Oh, all in small bits and it won't actually bother a live clam.
