Does anyone have any experience with horseshoe crabs? I recently got a very small, very light (light enough that the current swept him off the sand and into the water stream where he scared my fish and did stunts he didn't like until I pushed him into the sand), and very white horseshoe crab, in the day he burrows himself somewhere in a shadowy spot and doesn't move, but at night I find him still burrowed going through the sand. Is this normal behavior?
