The cup itself stays in place and does not move unless you apply very strong force to it. an important feature when your mysterious snail is a giant bulldozer pulling out plants. I mean seriously she runs around the substrate tearing up plants, I find her swimming all the time. Installing a tank as this tube often detaches from the wall when I have to lift the lid to clean. But even if it's free, it still doesn't fall, so I'm happy. I just press on it to increase suction again. I would recommend this to anyone who has invertebrates if you want to see them feeding and prevent food from getting into your substrate too quickly.
