Review on Aliyaduo 8 Pack Fish Tank Divider Set - Snap-Together & Easy-Cut Plastic Aquarium Separator Panels - Grid Isolation Board, Egg Crate Fish Tank Bottom Tray by Heather Schmidt

Tip: If you don't have a hammer, try placing a small hardback book on the snap connector and pressing down with all your weight. I prefer that to stepping on him. I bought this along with a window screen to make a false floor for a 4x2 planted reptile enclosure but after putting the 12 pieces together it sags in the middle and I can install any substrate on it. I suspect anyone with a huge aquarium will run into the same problem and need to make lots of PVC legs for support. However, it would be perfect for frogs and small lizards!
