I am not sure what is wrong with my snail. Last week we had an ammonia spike in our ten gallon and we lost three fish two cory's and our betta. Well now I am afraid we are about to loose our snail. All we have left in the ten gallon is three cory's and the snail. We had to put some medicine in for fin rot as well. For the last two days the snail has been floating on the top and getting pushed around by the filter. I haven't seen him moving about the tank for over two days. I am still new at this and I don't know what could be wrong with the snail. We did a water change yesterday and checked the water parameters. The ammonia is about 0 and the nitrite is high .... we have the strips and they are kind of hard to read but it said it was in the danger level. The nitrate was at 10ppm sorry if this isn't very helpful but as I said I am still new at this.
