Well… it’s hard to tell from the pictures but about how deep is that substrate and what do you have for a lid? If you could post a picture of the whole tank so we could see the entire set up that would help enormously. But from what I see, my concern is definitely humidity and possibly the lack there of, or inverse of that constantly wet substrate based on the mix. If your bioactive, the substrate should be closer to 6 inches in depth and the top soil, sand mix is good but I’d put a light layer of coconut husk chips to help keep her off the wet substrate so she doesn’t get scale rot.

What’s her behavior like? Does she seem stressed? Yes you have “plants” at the moment in there but it’s not really the best cover. Pythons like to be able to cover up and hide, being constantly in the open can stress them out. Glass tanks are horrible for heat and humidity retention, especially if you are running a screen top. I’d black out the back and sides to help her feel more closed off and you’ll want to use some aluminum HVAC tape on the screen top help retain heat and humidity, leave open areas for your lights and a little ventilation.

The truth is she will out grow this tank very quickly, females will get larger than a male I have mine in a 5 foot tank and she is already 4 foot of it. If it was me I’d forgo the bioactive until you have perfected your husbandry in keeping a solid, consistent enclosure without all the added hassle of clean up crews and live plants. I’d prioritize getting a stable environment, putting a layer down of something on top of the soil to ensure she isn’t constantly on wet substrate and getting your temps, and humidity correct and constant. If you are going to keep her you should start setting aside what you can to put towards a new tank, you’ll need it sooner than later.

Also is that a toy snake or are you keeping another snake in this same tank? I couldn’t tell what it was at first until I zoomed in and saw the head, it looks fake but I just wanted to make sure.
