I have a 20 gallon long glass aquarium I was going to house a snake in. It has a heating pad and I have a uv strip light on top. The whole snake thing fell through (the breeder hasn't contacted me in forever) and I was thinking about maybe getting a male veiled chameleon, because I heard the females are hard to keep alive (due to laying eggs). I went to a pet warehouse and they have these attachments that can go on top of tanks, they're like basically putting another aquarium on top of the one you already have but its made of wire. Do you think if I put on of those on top of my twenty gallon long (so it'd be a 40 gallon long, I guess) it'd be enough to house a veiled chameleon? I saw a baby at the pet store and they said since it's so little they recommended keeping it in a glass tank until it's a little bigger, but I want to know if that whole idea would work out at all and if so for how long. I'm hoping it'd be enough for when it grows all the way up, but I'm guessing it probably wouldn't be.
