My Chams sleep perfectly fine with the tv on. I belive my tv is a 50" (and a very sexy tv). The tv is pointed in their direction but they seem to be fine with sleeping behind cover. So long as the light isn't directly hitting them they are fine.
I would go with the red wigglers. Much smaller then your nightcrallers or Canadian earthworms and in nature they're found in the first few inches of the surface so they would do great for an enclosure. They make a great food source but they do release a bad taste when they are threatened so that...
Well first off what kind of plant are we talking about? All I see is a pothos. If that's what you're talking about then of the window Is exposing too much sun and heat it will not grow, pothos prefer a more room temperature type of environment.
Here's a book I highly recommend you get, it has an amazing article on bioactive substrate. Though the book is mainly based off snake husbandry it can be applied to other species as well
Hmm, that's interesting. I originally got my bioactive idea from monitor keepers and was told they all spot clean. I'm sure in a very large established enclosure it can happen. From what I've noticed is the springtail and isopods seem to show interest in the poop until it starts to dry after...
In the early stages I doubt it'll break down waste with any speed. Though the purpose of a bioactive enclosure is indeed to have a self sustaining enclosure Idk anyone other then dart frog keepers that don't spot clean (unless the frogs poop on the glass). Your lizards will likely poop much...
There's no reason to leave the poop. I spot clean all of my enclosures. The microfauna won't need poop to thrive it will have other sources of food like leaves mainly.
Though I'm sure your Cham would like p Nivea, they're a little harder to control and much faster. They can also catch flight very easy and take a little longer to mature in my experience. I would go with discoids.
