I change male E. plumbea for corn snake, milk snake, ball python, boa

Hello, after a canceled reservation, when the interested party did not contact me again, I am offering a young male of the E.plumbea species. I've had him for half a year, he came to me as a subadult and had 4 problem-free sheddings during that time. He is used to feeding 3 smaller aquarium fish once a week. He always catches them. He was kept in very hygienic conditions (like most imports), he was placed in a 50x30x30 box where he had 5 cm of water. It has a calm, non-biting nature, it only occasionally jumps out of your hand, it comes from an import from Indonesia, but in total it has been in captivity for 7 months. I would like to replace it with a classic snake that eats mice or chickens, since it is easier to feed the same food with more animals. It is 100% free of external parasites and apparently without external ones, as it eats without a problem. It is about 30 cm long. Overall, it can grow up to 40 cm. I warn you in advance that it has rear poisonous teeth, like a heterodon, but it is completely harmless to humans. Suitable for both pets and breeding. I'll trade it for an AD snake, coral or baby boa constrictor or python. Please only offer calm non-biting, well-eating and healthy pieces. The snake should be used to handling.
