I recently rescued a 6 year olf sand boa. I dont know their gender or their subspecies.
Any advice on housing, feeding, bedding, and enrichment would be appriciated!
Photos attatched for his current setup. It’s not shown in the photo, but the substrate is sopping wet and smells musky.
If you can post some photos of the snake, you will probably get better answers on which species it is and more specialized care. They aren’t really a species I work with personally though
That being said, if the substrate is wet and musky I would remove it. They need something they can burrow in and some humidity, but right now it sounds more like a hazard and breeding ground for bacteria.
^ seconded, I would put together a bare bones quarentine tank with paper towels, hides, water, and heating. This will let you keep a better eye on the noodle, let them dry out and hopefully avoid an RI, and monitor for mites, RI, or other illnesses.
I’m not sure if people use a specific quarentine set up for such a burrowing species, but paper towels and minimal ‘stuff’ is the norm for a quarentine or hospital enclosure
Definitely toss the substrate if it’s wet. I’m guessing this is a Kenyan sand boa (though sharing a picture of the snake will help confirm that), as Kenyans are the most common sand boa species in captivity.
Assuming it is a Kenyan, this is an arid species, so they SHOULD NOT have wet substrate. I keep mine very dry, only giving a very light misting when I notice she’s in shed (and even that probably isn’t necessary, because she’s shed fine when I haven’t noticed and misted in time).
Sand boas are fossorial, so while many species do well on paper towels, as @cmills suggested, that is NOT what you want for a sand boa. They need to be able to burrow to feel secure, so the most important thing to give them is several inches (3+) of clean, dry, loose substrate. Aspen shavings work great, but you can use pretty much any loose substrate that will hold a burrow. Sand on its own isn’t great (despite the fact they’re called SAND boas), because it collapses and doesn’t hold burrows. But aspen, ReptiSoil, Jungle Mix, coco husk, top soil, that recycled paper bedding they sell for small mammals…any of that would work great.
Aside from substrate for burrowing, all they really need for cage furnishings are a couple hides and a water dish. And some people don’t even bother with hides, because they usually just burrow to feel secure.
For temps, I give my girl a hot spot of about 90F, warm end in the mid to high 80s, cool end in the low 80s. And as I already mentioned, I don’t really worry about humidity. If I notice she’s getting ready to shed, I’ll lightly mist a bit, but that’s about it. Kenyan sand boas have a wide range in the wild that encompasses a variety of climates, so they can tolerate a wide range of humidity. But you do want to keep their substrate dry.
Thank you so much for popping in on this, I figured not being able to burrow would be an issue but had no idea what a clean quarentine alternative would be 
My sand boa was my first snake, so I wasn’t really worried about putting together a true “quarantine cage” for her, as there wasn’t really a need.
But I think if I were to get a fossorial snake now (and thus need to quarantine), I’d probably use that white paper bedding sold for rodents as quarantine substrate. Since it’s white, that would make things like mites or concerning poops easy to observe, and it would still allow the snake to burrow and feel safe.
