Anyone know what these things are?

  • We are currently upgrading MFK. thanks! -neo
Cool a sponge. Well the rock was never out of water except for a few seconds while I transfered them out and into the new tank.

Is there a way I can tell if they are alive or if they die will I know.

Anyway thanks for the help.
 
If its been setup a few weeks they would more then likely be fairly rotted by now if they where dead. If its just been setup you will notice them falling apart eventually.
 
Well its been a week and a half now and they still look exactly like they looked when I put them in so hopefully they stick around.
