Arrow Crabs

[Keen]

Does anyone have an arrow crab or two that I could buy/borrow from someone? I have a bristleworm problem. They are attacking my new turbo snails i put into the tank. I have read that arrow crabs eat them for lunch, so I was hoping that someone would have one for me possibly, since big als only has arrows with 1 or 2 legs, and im not buying a gimped crab. I dont have a car either, so it makes it hard to get to the other lfs. if you guys could pls get back to me, it would be greatly appreciated. I could also trade some green star polyps for the crab as well.
