Hi, my sister is getting a texas brown tarantula and I had a question about temperature. I don't have any experience on tarantulas more reptiles and I keep getting conflicting info on using a heat mat on the side of the tank, CHE with thermostat or nothing at all? She keeps her house in the 60s and it's going to be kept in the basement. In the winter, it also gets pretty cold here so I have that concern also.
