What's wrong with my mystery snail?
A few months ago, I bought my mystery snail and put it in a 10gal tank with 3 neon tetras. There were no issues, and he seemed to be fine. About a week ago, I bought 3 GloFish, and that's when problems started. I noticed that they were nipping at my snail, and that he started keeping his antennae in his shell (besides that he was acting normal). A few days ago I saw that when he was tucked in his shell, the "door" of the shell didn't close tightly, and some of his body peeked out. I know he's not dead because he's still moving around, but I'm not sure if he's getting enough to eat or if something is wrong with the water. Please help! (I just checked the water, and the nitrate, nitrite and chlorine levels were low, and the pH was about a 7.5).
