Reddit reviews Fluker's 51019 Small Animal Bend-A-Branch Pet Habitat Decor, Medium,brown

Looks like it's one of the coated wire variety, like so: https://www.amazon.com/Fluker-Labs-SFK51019-Branch-Habitat/dp/B0009YEB52

They're strong enough to support smaller snakes free-standing since it uses a lower-gauge (thicker) wire as the core. Just twist it around into a sturdy shape and you're good to go.

With aboreal species, impaction really isn't a risk. Your focus is more on keeping the humidity in the enclosure up constantly, which is where the coco fiber and similar mixes come into play. Eco soil mixed with sphagnum moss would be another viable option. Orchid bark mixture (wood chips/moss/soil/etc mixture) would be a third. With orchid bark mix, you'd have to find one that doesn't contain any additives and plant food. For example you would not want to just grab a bag of Miracle Gro orchid mix off the shelf at Walmart.

In regards to treats. I wouldn't do absolutely anything until he is routinely eating the Pangea. With food already switching, he needs to view the one new thing as food for a while. Once he's consistently eating the food that he needs to be eating, then you might worry about a rare treat. It would honestly be better to just get some different flavors of pangea to rotate through rather than go through the trouble of blending bugs and fruit and pollen. With how picky he already is, it's unlikely he'll even touch it. He'll settle into one flavor of Pangea and that will probably be that.

Another thing you can do to maximize the enclosure space in his current and future cage is to add some climbing vines (again, secure with twist ties, some also come with suction cups) and perhaps a piece of hollow driftwood (somewhat poor example, but something like this). Both can typically be found at a reptile supply store. The latter you might have more luck with at an aquarium store.

Make sure that the new cage is well ventilated. In addition, no need for UVA or UVB lights, or heat. They're a nocturnal species and room temps are typically sufficient.

In finality here, I say get rid of those vines, get ones like this.

Cresties love to climb, I saw some awesome mushroom looking vertical cage decos on amazon he'd probably love.

Edit: Couldn't find the mushroom ledges again but I found some other cool stuff:

Oh, he's the one that's been bombarding me for years with all of the reptile facts and care information on the planet. Even knows the best local reputable breeders. The terrarium I picked out is an ExoTerra 20 gallon and the branches I put on the list are a formable sort of branch that you can position. I read that they don't need a heated rock (I had an iguana when I was young that did require this) but that you can use bulbs in a reflector light fixture at one end/side.
