Interesting little event tonight.... I added a few snails to the tank from my established 40g fuge type tank. One of the snails looked like it was dying with its foot dissented. It wasn't totally dead as the foot wasn't totally slack but it didn't retract when touched either. SO I put it into the DT along with a few other snails. A few minutes later one of the snails was touching the "injured" one. It appears as though both are moving or perhaps on snail is eating the other? I guess if the injured ones shell is empty tomorrow I'll know.
