Ew, so maybe that wasn't a dead crab body I found today. It was lying next to a pile of mush that I thought was disintegrated crab. Hopefully it was just exoskeleton.
I give mine to the kids to take to school :headshake2:
The first time they took them for a show and tell (a talk to the class about our tank ) now they take them to scare their friends:eek3:
Its a good indicator of excellent water conditions with all things being well in the aquarium
