Poor crayfish

We bought three crayfish a few weeks ago. Two of them disappeared almost instantly, which I thought was a little strange. They are like tiny lobsters, how could they disappear? Fish can't eat shells. Or maybe they can. Anyway, the third one was fiesty. He excavated gravel like a madman, and made a huge tunnel under a log, and that was his home. He usually hid out under there, unless it was time to eat. Excuse the really bad picture of him at work.

Jeff and Jake were bonding over a car show, so I was watching the fishtank. I see the crayfish come out from underneath his log, climb over his gravel mountain, and sneak up behind a plecostomus that is easily three times his size.

He reached over with one of his little claws, and pinched the pleco right in the back. The pleco jumped like, well, like something just pinched him in the ass. The crayfish ran back over the gravel mountain and underneath the log.

It was a couple of days later that I noticed what looked like a part of the crayfish's shell floating on top of the water. No big deal, as they grow, they molt, and leave their old shell behind. So I reach in to grab it, with my bare hands. Mistake. It. was. soft. *shivers*

So I am thinking that the pleco had enough of the pinching antics, and had himself some crayfish sushi. Poor guy just wanted to have a little fun. *Sniff*
