Boyfriend’s Pets

Hello I joined this sub to get some insight on my boyfriend’s pets. He’s had these lizards since they were babies, I have been with him for a year now. I’m an animal lover myself but have never had pets this exotic before so I don’t know much. But I often wonder if they have enough enrichment in their enclosures and if they’re getting enough of what they need. Are there some items I could get him to up their habitats and make them seem happier? They seem to like to climb, and hid themselves. Am I just overthinking it? He says they’re fine, but I honestly feel sad for them? Any help is appreciated:)
