The hides might be a little big for a hatchling but it’s hard to tell in the photos. Just remember for them to feel secure you want the hides pretty snug.
Re: whether or not to take out the cool side hide etc, I’ve always been a proponent of matching hides on each side, never had a problem going that route.
But otherwise, looking pretty good so far.
How are you heating the tub, regulating heat, and measuring temp/humidity?
Also, make sure you’ve got some airflow in the tub via holes.
