They're right, you do need to get them to a herp vet. Remember, the advice you get on this site is not veterinary advice. If they're housed together they need to be in separate enclosures. If spot has parasites and dies, pepper can be next in line. You need to get them checked out immediately. Even if you have a pet store near by that sells snakes, ask to speak to their snake specialist. They may suggest force feeding, but it's very hard and can be dangerous, for the snake and you. You may need to administer a vitamin supplements. It is urgent if you believe you're going to lose one. Do you have pictures of them, or the enclosure/s? If we have a visual we can help more.
