There is also one called "Had a snail". But I disagree with snails being bad for an aquarium. While I try not to let ponds snails in, I went and bought applesnails and Viviparous snails. And I got a load of MTSs. They are a natural element of the aquatic environment. But of course if you have too many of them then you could use chemicals but there are other ways. The chemicals are also tough on plants. You can just add a few pennies to the tank, copper is poisonous for snails, but in small quantities will not harm fish or plants. Or use an old pill container, puncture a few holes into it and place a lettuce leaf inside. Leave this in the tank for a night and remove the snails in the morning. If you do this a few days in a row you can get most if not all the snails. I do this to capture the snails in a 1.5 gal where I raise them for puffer fish food. This is the easiest way to get them and it works every time.
