I recently switched from a 5 gallon tank to a 2 gallon tank. I used to have three goldfish and 1 beta and a snail. Now that I am down to just the beta and snail I thought a smaller tank would be fine. I put Gary(snail) and Elvis(beta) into a 2 gallon bowl and they were fine for the first week, but this past week Gary has been laying on the bottom of the bowl and I can't tell if he's dead! When I touched him in the bowl he didn't move and he had a ball of slime around him, I took him out and he was just hanging out of his shell, when I rinsed him off I could have swarn his foot was moving but I don't want to get rid of him if he's alive, I have him in a very small dish now and he isn't moving again, Is he dead?
