I'm loving the name you gave your snake- it's nice to know I'm not the only one that thinks of enchiladas when you say "enchi"!
For a BP to go from a 20 gal to 150 gal enclosure is a HUGE difference- not all BPs seem to like that much space, unless it's made "cozy" with lots of furnishings. But as you said, that's off in the future some time, anyway. I wonder if it might help a snake to feel less scared & "lost" if they got multiple short visits to the new enclosure before they actually move into it??? I honestly think that's what I'd do.
Think I figured it out lol.Thanks a lot. So here is my male enchi het clown And for the 150 gallon I'll put a lot of plants and hides so I think when he'll get bigger it could be good. He'll be in a really calm area of the house.
