Heres my story:

I got my new baby BP on October 8th (my first BP). He was pretty small in size (not sure exact weight at time of purchase) but he was really friendly in nature and I really enjoy his personality despite the small size... I moved him into a 16qt tub with complete heating/accurate temps and humid as well as "hot spot". The staff at the breeding facility told me he was eating, every five days or so. She told me he was eating hopper mice. For the first two weeks, my BP, Loki, readily took frozen/thawed hopper mice. However, on week three of owning him, despite attempts every 5 days or so, he had no interest in the frozen/thawed hopper mice and acted defensive, going back in his hide. I noticed he seemed stressed inside his enclosure more so than out, as he loves to explore anytime I hold him (which isn't often either). I weighed Loki at approx. 50grams last Thursday, so I figured trying live feeders would be better. A live hopper mouse scared Loki. He showed little to no interest in the rat pups and got frightened and retracted defensively anytime one moved near him.
I decided to move him into a smaller 6qt tub, which is about the size he was house in at the breeders. Tonight is his first night in the new tub enclosure. I am not too comfortable with housing snakes in fish tanks so I really want to avoid this... I read that 6qt is a good size for small babies who aren't eating, correct?

Anyways, does anybody have any advice to give me on feeding my precious bay Loki?!! I worry so much now about his weight I really want to breed him eventually let alone house more snakes and I want to do it right. I plan on building rack systems in the future but for now just his tub is all I have. The temps and humidity are all perfect. He probably will need a night or so in the new enclosure to feel comfortable again. But I do continue to wonder if I should attempt assist-feeding or not. I was not told the age of him when purchased but if I had to guess I'd say within the past month or so, because he was tiny at the time of purchase.

Hope I included enough info. Any help is so appreciated. I can't upload pictures of him right now but can tomorrow...

Thank you so much,

Linz
