Snails are a useful part of the tank ecosystem, but definitely super annoying when they take over and make everything ugly. I do find bladder snails kinda adorable, but my population died out somehow! The shrimp didn't, and didn't use copper, so wasn't meds or anything. But I have no qualms with baiting and crushing the teeny tiny species of ramshorns I deal with now. Hate them. My MTS also often have population bursts, and I need to use a little sifting thing to sift through the sand and lift out loads of MTS. Those get binned - I feel sorta bad about it, but their shells are too hard to easily crush.
When people talk about over-feeding, I don't think it's so much saying that the snails will die. It's more of a thing that if there's a load of extra nutrition in the tank from excess food, loads of organic decaying plant matter, substrate not cleaned much - that the snails grow faster and better, and are encouraged to breed more and sooner, leading to a rapid excess number of them that then also start breeding. I know that if I've slacked on cleaning or I've been feeding a lot more because of fry, that's when I've had excess numbers.
I'm happy to have some snails, they do help break down organics, even consuming dead fish sometimes which can help prevent an ammonia spike. When they expode in numbers, I take it as a sign that I'm slacking somewhere and need to do a thorough clean and ease up on the feeding.
I also use a net to swipe MTS off the glass once the tank light is off/first turned on, and otherwise, bait them with algae wafers or similar.
PLEASE, DON'T RELEASE ANYTHING FROM AN AQUARIUM INTO THE WILD/OUTDOOR WATERWAYS! This is how aquarium diseases wind up spread into the wild, non-native species end up damaging the natural ecosystems etc.
Also please don't but fish just to deal with snails. For the reasons outlined by
@Naughts . Hate seeing people advise getting a yoyo, clown or similar botia loach for that purpose. Yes, they're great snail eaters (but bear in mind that once they're a bit bigger, they won't bother with tiny snails anymore) but they're also fish that get pretty large (clowns Get MASSIVE) and NEED to be in a social group of five at the absolute minimum. They're intelligent and social, and suffer when kept in ones or twos. Only get loaches if you want them for them and you're prepared to give them the kind of tank they will need for their lifetime.
I always highly recommend this brilliant article by our very own
