So, I know this question of which is better, tubs or tanks, has been answered literally a million times and I apologize for bringing up again, but as a soon to be first time ball python and overall snake owner, I really wanted answers and results that would tailor specifically to my situation. So... my step-father placed an order at a reputable reptile shop in northern Chicago (I live right above the Illinois/ Wisconsin border by the way), and from what I was told, it is going to be about a month for the snakes to hatch and weigh about 100 grams until we can drive down to go get him/her. I could not be more excited! He also said he purchased a 20gal tank, along with the essential equipment as well as some substrate among other select things. I was concerned when I first heard this because I have read and seen many professional snake owners/breeders/etc. say no matter what, tubs are the way to go. And I guess my big questions that I would be so grateful to have answered are... Is a tank substantial for just one very young ball python or is a tub more efficient no matter what, even if I only have one baby? I just want it to be as comfortable as possible so it can have a long and healthy life under my guardianship of this beautiful creature.
Note: I've read a lot of the past threads about this discussion and I wanted to say two things: If I do find out a tank is perfectly fine for the only one ball python that is soon going to be in my possesion, and I've read that them seeing everything around the room can stress them a bit, would paper or something like that work for blocking visuals on the three of the outer sides of the tank? And the second this is: If the tank does somehow seem to be unfit for the proper care of this creature, then I will immensely switch to tubs.

I greatly apologize if this is any way confusing, haha. But I would be so grateful if my questions were to be answered since I've witnessed hundreds of knowledgeable people on here answer tons of questions I used to have. Thank you so much
