Juveniles are more aquatic than adults but what they really like is for the larger part of the year is to hide in holes which are partially flooded.
I keep them with looooots of hiding places that range from emerged but moist, to completely submerged. They choose what they like at any time. The open ares are very shallow and there is a small area of deeper water just in case they feel like getting a swim which they sometimes do and to encrease the volume of water and facilitate maintenance and water quality.
The first picture is what their previous tank used to be like, and the second their current one. You can´t really see in the picture but it is a maze of bricks and crevices.
