I was told this is a good temp because if the cham gets to hot he will move himself to a cooler location thats right for him... also i was told the calcium D3 was Crucial and that the calcium and multivitamin were useless.. iv heard this from a few people and it makes this whole experience very annoying that everyone has different information. I will move the lamp further away and get calcium.
You're far from alone in having been given misinformation, which is why this forum is a great resource for people who want to do their best to ensure that their chams have long, healthy lives.
When I went into a local pet shop seeking calcium without D3, I was asked, "Why?" because they had no idea that too much D3 is bad for chameleons.
They just didn't know any better.
It is beyond me to understand why anyone with any real world knowledge of reptiles would say that multivitamins are useless.
In the wild chams eat a variety of insects who are themselves eating a variety of foods.
At home, we offer very little variety, by comparison, and so those feeders should be fed a variety of foods to make them nutritious, rather than just a source of calories.
Dusting the feeders lightly with a multivitamin 2x a month will also help to prevent vitamin deficiencies.
You will boost your cham's health by doing this and by following the caresheet.
As for the UVB bulb, there are 2 very different All Living Things UVB bulbs sold by petsmart.
The one for tropical lizards should be ok. The one for desert animals is too strong for chameleons' eyes.
Yes, a chameleon will move to a cooler spot in the wild but in a cage, a too hot basking spot creates a dilemma for him.
He has to choose between too little UVB and lower temperatures OR too hot a temperature with the right amount of UVB.
Either way, he can't win.
That's why it's better to offer a basking spot with the right basking temperature.
