I am bathing both my tortoises daily right now, for about 15 minutes. they really enjoy bathing. i saw my tortoise use his arms to splash water on his own shell. I let them out in the lawn to eat grass. I am going to start letting them eat the zoo med tortoise food and mazuri tortoise diet food.I will post pictures of both of them in a few weeks to see if they look any better. Also i am going to build a habitat in a few week as well.
Glass enclosures left out in the sun get ridiculously HOT. I have a friend who's wife put 3 baby leopards outside in a 20 gal long glass tank and she killed them. They were dead when she went to check on them. Basically cooked them. Just be careful.

And nobody said anything about the spinach thing??? It's ok to give them spinach once or twice a month, but they really shouldn't be eating it in huge quantities. It's nutritionally bad for their livers and stomaches !!! if you feed her off with too much spinach they will develop serious illnesses !!
They look fine. We can only see so much from the appearance of their exterior in a pic. If their care and diet routine is good, they will remain healthy and should start really growing for you in the next few months.
