Hi, I've had an apple snail for about 3-4 years... he's been through alot... from moving cross-country and having his glass jar dropped on the sidewalk, to my cat scooping him out and playing with him on the floor! Anyway, after the move about 6 months ago, I've noticed his shell started deteriorating... it is in bad shape.. although the tissue underneath seems calcified. Well, we recently started up our 25 gallon with some dwarf gouramis and decided to add him in... within minutes, one of my flame gouramis bit his antenna off!! So, I moved Gary (the snail) back to the 10 gallon on his own. Now, he seems kinda freaked... comes out to eat and then hides again... been floating alot lately - much more than usual... I know this sounds strange... but he seems miserable! How long do snails live? Should I put him out of his misery - I've heard that putting them in the freezer is the most humane way??!! I've also noticed that I have 5 baby snails in my 25 gallon - I assume came off my plants... but the gouramis aren't even touching them!! Need advice please.
