I bought this used acrylic tank off of Craigslist which is about 300 gallons. I think this will make a nice size swimming area for the large pair of caiman lizards. The cage area will be about 8 feet by 14 feet long and 6 foot tall. I leveled the ground and placed the tank on a sheet of foam to help even out the weight between the ground. I have bought a new pond filter and heater to install at the end. I will try to post updates as I make progress but I'm expanding the tegu cages as well so we'll see which one makes faster progress.
