A friend of a friend grows rice in Thailand. Non-native snails are destroying the plants before the rice can be harvested. Do you know of a way to get rid of the snails without harming the plants?

Answer 2

Never release your snails in local ponds or rivers, in some countries it is actually an offence to do so, if they are not native to that area you could be introducing a new species that could be harmfull to the enviroment around you, I would take it to your local pet shop and they will be able to identify what sort of snail it is, sounds like you could have a good business going if they are interested, also if they are becoming a problem in your tank then I suggest either selling them or giving them to the local pet store or buy a fish that thinks snails are a delecasy, CLOWN LOACHES are a beautiful peaceful fish that LOVE snails, a few of those will certainly help your problem as long as they are compatible with the other fish in your tank, if it is a pond I would not add these. Pet store is your best bet tho.
