You are looking at a used 20 gallon glass aquarium w/metal lid. This also includes a woodlog, water dish, and tree. We used this to house two anoles (small lizards). It measures 20" x 12" x 10". It is in excellent condition with very little signs of use. We only used this for about six months.
The items that I list are of good quality and something I would purchase. I am not trying to sell something that needs to be thrown away. I strive to be honest and accurate regarding item descriptions. All sales are final.
