Does anyone know how to care for a bobbit worm?

I went fishing with my friend and I caught a small bobbit worm, I first thought I was a bristle worm and decided to put it in my mini complete tank as one large single clean up crew. I now know it was a bobbit worm as when it started digging, one of the amphipods in the tank went too close and... rip amphipod. The bobbitworm is pretty small, it about 2 inches. Do bobbit worms eat coral, the only coral in my tank is a xenia frag my lfs didnt wanted and I got it for 5$. Will it be ok with it. Does anyone know care requirements for them.
