I’ll also add this as this is also how we had our chams viv. All bioactive with isopods and springtails. I recommend bio highly, plants etc also as they drink from them. I do not recommend paper towels at all. Our boy was in a 60x45x90cm exo terra and the clean up crew was amazing! No clue as to why people think the crew won’t clean the poop well as we never had an issue ourselves 
And he was in bio all his life 
We didn’t so feeding ledges as food get out of cups. We put the crickets etc right in the viv and watched him hunt them 
Males are bright coloured, females tend to be pinky!
