Beware though. Fully grown Clown Loaches are capable of reaching 12"+ so need a big tank to grown into. They are also a menace to plants so are not an ideal snail solution for many people.Also, i had this problem a few months ago and i got three clown loaches to get rid of them. They did an AMAZING job. I havent seen a snail since. The only problem after that is getting rid of all the shells which can throw off your water parameters. Good luck
