Okay clearly there's a lot of people who wonder about this, and the answer is never certain, so maybe there's no real way of knowing:

HOW MANY AIR HOLES DO I NEED??

BUT WAIT, before you reply with "it depends on your [environment details]", let me be clear. I am not asking the how many to maintain proper temps, proper humidity, maybe not even "sanitary" air flow. The question is simply:

What is the minimum number of air holes needed so that my snake does not suffocate over time?

Now, I realize this is maybe something that people just don't know for sure, I'll take that. And I also understand that snakes use much less oxygen than humans. But is there anyone who is relatively certain of how low on air holes you can go? Because I feel like I could poke a pin size hole, have a tiny water bowl, and the humidity in a large tub wouldn't get so high but the snake would suffocate.

I have been desperately searching for an answer, only to find answers that are about *how* to make air holes, or *it depends on the environment*, and I really want to know if my snake is just plain safe with X number of air holes.

Note: Let's say one air hole is a pencil sized hole in the side of the tub, and I'm assuming right now that bare minimum regardless of oxygen flow is one one each side (but would that theoretically be enough??)
