My nephew has a young corn snake that regurged it's pinky meal. It was his first feeding and I found out it had no belly heat. I told him to wait 2 weeks and try feeding againand suggested an UTH but the labeling on the package says glass tanks only, no plexi/plastic/acrylic and he is using an acrylic tank. Hmm, suggested a 12"x12" stone flooring tile for beneath the heating light but don't think that will be enough. Thoughts?
