Sorry, I should have been a bit clearer. They each have their own tank, so yes, they are great for a baby right through adulthood. The key is a lot of hides so they are able to move from the warm side to cool without feeling like they are out in the open and vulnerable to predation. It doesn't take them long to get settled in and be out in the open without a worry, but a wee baby does need to feel secure.
