Honestly Animal plastics just look really ugly to me :/ I do have sides covered (I have a background stuck on the outside of the tank that looks all jungle-y)
plus I’ve read that PVC goes bad and breaks down over time.
I’ve worked out the humidity and temperatures in my 20 gal glass so I’m sure with a few more modifications I could work out the 40 gal as wel. Besides animal plastics don’t sell on amazon and I have like 500$ on there as a gift card balance
