Assassin Snails

There was a discussion on here recently about Assassin Snails in which I commented that my folks had some but they hadn't made any inroads into their pest snail population, however they were breeding so hopefully the increased numbers would make a difference.

Well they have - when visiting on Friday I noticed that their pest snails have been almost entirely cleared out!

Which brings me to my query; once all the pest snails have be assassinated, will the assassins turn to 'normal' snail eating practices, i.e. not starve through lack of mollusc related snacking? 

Here is an article on assassins (and Sulawesi snails). The author is one of the most respected writers in the hobby. He covers both of your questions   

Interesting article. Thanks Sue.

After reading it I have just bought 10 of them from eBay. Hopefully they will control my ever-expanding population of Malaysian Trumpet Snails.
