When the weather is warm and sunny, I put my scorpion's tank outside with the lid up so he can have fresh air and sunlight. I mean obviously he's under his rock or bark, though he will come out if the tank gets too hot, but that doesn't happen much because I make sure there's some shade for him too.
One time, I forgot, cause I was having lunch, and when I came back out, he had got the food bowl (for the crickets) and had put it on his head like a hat, it was very funny and cute. I took some photos, which I will have to find and post here.
Anyone else put their tank outside?
