I've got one turbo snail that's gotta be pushing 5 years maybe more. Don't get me wrong they are great if you have algae issues, especially stuff like the pink cotton candy or crazy amounts of hair algae but I no longer need them and I'm just waiting for the poor old snail to die. He's the last one and unless I have future algae issues I will stick with smaller snails. He can knock off glued frags without issue.
