We now have a good supplies of Assasin Snails for sale. These snails will kill and eat most pond snails types of snails. They do seem to work, but if your aquarium is over run with pond snails and you only put one or two Assasin Snails in. Then there is no way they can do their job fast enough.
Some peoples say they will not kill the large Apples Snails but other peoples claim that sometimes they will. Some peoples claim they are safe to put in with Shrimps, while others claim, they had seen them attack and kill Shrimps. I find it hard to belive that they can kill Shrimps, because for one things Shrimps can move a lot faster than them(Assasin Snails).
