Hi, I have just a small aquarium with a couple of fish in it and my snail (that I'm quite attached to!!) Last week he crawled out of my tank and fell onto our tiles, cracking his shell and generally shaking himself up quite abit. We thought he was dead until the next day when his tentacles (I think that's what they're called) came out. He now sits in the bottom of my tank (hidden from my fish so they don't eat him) but doesn't move. He has opened up underneath a bit, but won't actually move around or go to the surface for air. I'm worried he'll starve or suffocate. Has anyone experienced something similar. Your input would be appreciated. Thanks.
