I received this with my rescue juvenile corn snake. I just replaced the screen in the lid with aluminum window screen material. The lid locks with a pin and slides out, as seen in the pictures.
Measurements are 20” wide, 10” deep, and 8.5” tall, equals a 7-gallon tank.
I would recommend this enclosure for a baby or juvenile snake, leopard gecko, or other ground dwelling baby reptile. Not designed as an aquarium, but a terrarium.
