I read this: http://www.yamatogreen.com/MalaysianTrumpetSnails.htm
and I take back what I said in terms of worthless. They seem to be quite special.

But will the assassin snails multiply like the mts?Yes.
I would not get a loach to get rid of snails.
I used to have one (seriously) MTS and one day I saw about 500 super tiny MTS. They never really increased in numbers, and eventually that generation started shrinking and I still had about 500 but in all different sizes. Then they just started to disappear again and now I am back to only a small amount again. I wouldn't really worry about MTS too much, but if you really feel the need to get rid of them, assassin snails are the least invasive option.
