What is a CHE? My tort has a heat light light that puts off no light. I was going to get her one yesterday, but they were out.Do you have a CHE? That would keep her warm without the gross pink and purple. Think like a tortoise - where in nature does a tortoise EVER have that sort of light. It could easily be part of what is keeping her sick. Her brain can process normal light; the funky colors could be so confusing that its like being spun in centrifuge and taking her energy away from getting healthy.
