HI All. I have a Nerite snail I think is a goner. He was stuck to the glass for about three days, not moving. Water tests were all good. I did a partial water change yesterday, and he was above the water line for a while while I changed H2O and gravel vac'd, so I moved him to another area of the tank onto some gravel near an area with lots of algae. He then crawled about two inches during the course of the afternoon. He has not moved since. Tonight I used my net to just nudge him a bit, and he flipped over, and it looks like a bit of his body is sticking out. I flipped him back over into a position where the fish could not hurt him. My tank has lots of Algae, so he should have lots of food. I throw in an algae wafer in now and then also. I have had the snail about 3 weeks, and he was really thriving until recently. I have not added any meds or anything new; just Prime when I do a water change. Any insights would be appreciated.
