This morning as I was leaving for work I noticed Octane in sand disguise curled in the front corner of his tank. Very unusual as he normally does not come out until about 2:00 in the afternoon. When I got home (later than usual) he was "still" sitting their sort of ball shaped. Definitely scary until he moved a bit and I noticed the new clam (empty) tucked up under his web. I am still not sure if the starfish open it and he plunders or if he has found a way to kill the clam without damaging the thick shell. Needless to say, I put another in the tank tonight and tried to film him. This time the clam was placed near the front of the tank and he spent the better part of an hour going back and forth planning an attack. Then the lights went out and he decided it could wait until morning.
