A week in a half ago I bought 3 turbo snails to help with algae. This morning I noticed that one of them was sitting on the bottom of the tank but still attached to the wall. We were getting ready to leave for the day so I had little time to watch it. When we came home it was half way up the wall so I thought it was ok. Later I heard a clank and looked...it had fallen to the bottom. I picked it up and held it to the wall until it attached, but a few minutes later it fell again. We've repeated this several times and it just seems to not be able to hold it's suction. I gave up and placed it on a rock. It moved on it until it got to the slanted part and then rolled off. Does this mean it's dying?
I checked my water and everything's fine. I had just done a PWC
