Reptiles and amphibians are some of my favorite animals.However, keeping them requires the use of special equipment such as the turtle tank filters land and water habitat. What is so cool about this product is that it allows you to split a waterproof terrarium automatically into a half-land, half-water environment. This sort of divided environment is especially ideal and well-matched for frogs, turtles, and water dragon lizards. Rather then trying to separate the enclosure on your own using rocks and piled substrate, this neat tool does it for you so simply. Once you try it, you probably won't ever want to go back to doing it manually. You'll want to set up one of these in every single one of your tanks.
