Blind snakes generally eat termite and ant larvae (not fire ants). They are real easy to keep if you can provide that food, but whats the point? You'd never see it. They spend their entire lives buried in the substrate. The only time they really come out is during the spring rains when the ground gets saturated. They often make their way up water pipes and are found in bathrooms and kitchens.
Cooler temperatures, moist but not wet soil substrate. It wouldn't really need any other cage furniture.
