Arrow Crab Eating Bristle Worms

He is some what of a "Psycho Killer" like Talking Heads sang of in the past...

How is Mr Arrow doing the frag tank in the basement? See for yourself, I think he is pretty fat and happy...

When I did my initial tank cycle, I had rock that was very well established from years in my 65 gallon tank (now my refugium in the basement). That rock came in with a healthy population of bristle worms and the process of ghost feeding the tank during the cycle did wonders for that population.
In my initial clean up crew, I included an arrow crab, based on some research that showed this is one of the few natural predators that the bristle worms can have in home reef tank. The intent was to get Mr. Arrow to eat down the excess amount of bristle worms I had and balance things out.
The problem was, this specific Arrow crab had more of a taste for my hermit crabs than any of the bristle worms, which I tried to fix by moving him to my frag tank and feeding him worms from the display, when I found them.
