So recently my fish got some kind of fungus. I went to PetSmart and got Marineland All-In-One Remedy. I put 2 tablets in like the box said to do and things were OK until my mystery snail fell off the side of the tank and landed directly on one of the tablets. He then closed his shell right on top of it and it was locked in his shell with him for 2 days. He didn't move, go get air, eat, or even poke his anything out until i put him in a separate container with conditioned water. Well now he is kind of moving his feelers around and his siphon doesn't want to seem to go up anymore, it kind of strokes the outside of his shell. He wont eat and he looks like he wants to move around but i don't think he can. His little foot or body is now a different color then what it used to be. I put a slice of zucchini in there for him along with an algae wafer and a romaine leaf but nothing. I really don't want him to die, he's my little angel is there something i can do?
