Also, glass tanks are not ideal. They are prone to jump in to the glass and hurt themselves. Better to cover all sides if you can - except the front.

Water dish is way too small. It is a WATER dragon. They need room to swim or at least fully soak. So it needs to be deeper and longer.

Keep an eye on the substrate and the poo. They are prone to eating it and you may notice wood shavings in the poo. This can lead to imapaction.
