one could argue that lower temps no higher than 85, like you and others mentioned, are also just an opinion
i looked at the thread made only july 2020 (4 months ago) claiming that lowering the temperature extends the longevity of their lifespan, but it wasn’t from a scientifically peer reviewed article, and again, there is no scientific evidence to back any of this up. if there is i would love to see it, as im always into improving husbandry
however, if you and others on this forum want to test this with your yemen go ahead, but it doesn’t seem wise to give this knowledge to new chameleon owners, and bash someone giving already widely accepted advice into saying it’s their “opinion”
