I placed my new crocea +3 days high up on the rocks, about 12" away from my 10k 175 Watt MH. Every morning I find him on the sand bed or lower in the rockwork. Is this becuase it doesn't like the location, or is it trying to bury itself in the rock and inadvertantly falling/moving? The clam extends nicely during the day, doesn't appear to be gaping etc..
