I was looking at enclosures for squirt, who is a sulcata about 5 months old maybe. He is currently in a 20 gln tank and i feel like he needs some more room, even though the aquarium is good for the humidity. I saw this storage bin at walmart and i thought it was perfect, the lid is split in half so you can leave one side closed and one open. But with the lights being clipped onto the sides i thought it might be too hot for him or even melt the plastic because it is so shallow. it is about inches deep. Any suggestions?
