Need to remove snails from your tanks? Wether they are friend or foe it can be very difficult to remove these invertebrates. The Dennerle Snail Catcher allows you to safely catch snails off of the walls of the tank by a roller scrapper which then puts the snails in the collection compartment. The catcher also has a telescopic handle and thus suitable for differnt depths. 
We have been using this to remove pest snails from our tanks and have had great success!
