Thank you...
...Iris and Mare. But unfortunately, I read your posts too late and he has fed again. If he regurges again, I'll wait longer. Please also note that, in the post, it was 7 days between feeds; "Five days later, he had his first shed since I've had him. I waited 2 days, and offered another meal ...". His temps are usually 77F at one end of his enclosure, and 84F at the other, and I have not handled him except to clean his environment twice since the initial attempts at tease-feeding. As far as internal parasites, I have no way of knowing. The breeder is reputable, and is a vendor at the local monthly reptile shows here in South Florida. He is accessible and very friendly and helpful. Hopefully, with his help, and the help of the knowledgeable folks on this forum, this little baby will thrive. Thanks again.
