I got a surprise this morning. It looked like there were two yabbies in the same tank. How did the other one get in there? <_<

Upon closer inspection it was only 'yabbayoys' skin.

Does anyone have experience in this area? I was wondering how often they do this and do they stay quiet for a few days before and after?

I noticed that lately he wasn't eating as much as usual, guess he was all full up.

I think they kind of go dormant right before and after shedding.
