Nope, I do have a few cleaner shrimp who have evaded it so far. In my experience so far, as long as it is well fed it leaves everything alone. When I first put it in the tank ( I had it in another ) it did try to snack on a hermit...probably should have fed first. But since then nothin bad, and that hermit is still alive and kicking.
Im more concerned about those chromis buzzing around while feeding and it getting confused, they dont see so well it seems. So when I feed I usually feed the fish on the other side of the tank to keep them over there.
