With you being in Florida I would think there are some local reptile expos. Here in Ohio I get most of my feeders from a expo held monthly. When I do need to order anything I like using joshsfrogs.
I don't use any type of heat source on my bsfl, just room temperature. It probably takes a little longer to pupate and hatch this way though. I divide the larvae up into several condiment cups on a shelf until they hatch.
I get most of my plants from Lowes and Menards. If your ok with starter plants in 3-4in. pots stevesleaves.com has a amazing selection. I've got a few anthurium plants from there that are doing great in my enclosures.
I received my calendar today and I'm very pleased again for another amazing calendar. I want to thank thank everyone in the forums, @Brad, his amazing team and members for sharing their gorgeous chameleons. Thank you all ❤️
The background color IMO is a personal choice. Funny story but all of my backgrounds are cheap foam rubber yoga mats and kind of like a neon green 🤷♂️
I like joshsfrogs.com for a lot of my feeders, anything from Black soldier flies, Blue bottle flies, several sizes of crickets, super worms, hornworms egg crate flats ect.
Normally gout appears in the ankle area, I don't really see anything wrong with his back as you mentioned. My concern would be sleeping during the day, double check all the temp and humidity numbers both night and day to see if they match up with the guild you are using.
