My pink toe is my favorite because he's so mild-mannered. I've noticed that as he gets older he goes higher and higher in the tank. When he was smaller, he actually used a log hide on the ground.
There's some debate surrounding the concept of target temperatures for tarantulas. In general, if it's a comfortable temperature for you then it will be fine for your tarantula, as long as you don't actually start to feel cold. To the best of my knowledge a bit of a drop in temperature every now and then is no big deal.
Congrats on the new little pink toe! Quite a looker!
