Arrow crab and clown goby compatibility

[Porcupine Reefer]

I have a population of bristle worms in my tank, and thought about getting an arrow crab for bristle worm control if it gets out of hand, but i have a yellow clown goby. My tank is 5 feet long and is 125 gallons, will they be compatible if well fed or will the crab start eating everything in my tank.

In theory, yes, if its well fed. Getting a small specimen will help, too. But how will you know if it's well fed? You can't really. I would suggest getting a wrasse instead.

Which kind of wrasse would I get? I already know about the reputation that six line wrasse have.
