Nancy said:The best way to track the clams is to put the ones you are using for that particular feeding in a shell or a little plastic lid so they can't burrow into the sand.
That's what I'll probably start doing...it will also give him something of a feeding area.
He's spent most of the day hiding just inside a piece of PVC where he can watch the room with one eye. A few minutes ago I tossed a clam into his den and he didn't waste much time before pouncing on it.
I'm pretty paranoid about him just because he's so tiny! It seems like anything could happen to him!
