the scooter blenny is actually a dragonette, not a blenny. but the bicolor blenny, at least mine, so peaceful so maybe she won't have a problem. I think some of the larger blennies could be a problem though, depending on what kind of goby. I think a blenny could probably harrass a scooter or other dragonette
