I have about 20 assassin snails to GIVE AWAY!!! I used to have about 200 pond snails in my tank so bought 6 assassin about 12 months ago. They've totally cleared the tank of pond snails and now decided to breed, so I now have about 25. I don't want any money for the snails but you would need to collect from Stoke on Trent. And don't worry you don't need to take all 20, I can split and give away as many as you like.
