Part of his problem is he's such a wuss. Are hippos always so skittish even after being established in the tank for a while?

The automatic feeder goes off regularly, and the others hover near the top like pavlov's dogs. The little hippo waits in the back of the line like a timid puppy. When a new occupant is added to the tank, Elvis hides while everyone else investigates.

There's not much LPS left for him to destroy. I've removed the one he was terrorizing. What am I going to do with a submissive three inch coral eating tang? :(
