Brought home a few trochus snails today.  Went through the trouble of drip-acclimating them, very carefully took them out of the bucket, and gently setting them on the rockwork.  But the last one, I accidentally lost my grip on him, and dropped him.  I watched in horror as he fell through the water, and landed in a cage-cave in my indo rock.  
 
 
now he's stuck in there, no way to get him out, and I feel bad.  

   I'm not removing all the rockwork to get him out, as I don't want red-ball sponges dieing again messing up my nano's water again.  Hopefully he'll have enough to eat in there for the rest of his life lol.
