I just picked up an organge spotted goby! Does anyone or has anyone had any experience with them. I know that they typically live with a shrimp which digs/maintains their hut but will the goby dig its own hut with out the shrimp? Also, does any one know where one could find one of the symbiotic shrimp the add to my tank? I heard it is pretty interesting to watch. Is the shrimp reef safe or would it be a terror?
