Arrow Crabs Reef safe????

Well they are generally considered reef safe but everything that lives on a reef eats on a reef...... If a wayward goby or small fish gets near them they will probably eat it. If you have a bristleworm overpopulation its worth the risk IMO. They chow down on worms. Ohh yeah they might also eat other worms such as coco or featherdusters, so if you collect those beware.
