I just moved my female spider to a 14 quart tub. I couldn't find any 12 quarts, but this one is small just a little higher. I put a cubby hole(black one) in there with a small water bowl. I think she will do better in here. Question is, how many holes do I drill into the top of it in order to maintain proper ventilation. I know this is a good way to control humidity, but she needs to breathe. I drilled 22 small holes all over the top. They are definitly not big enough for her to get through and they are scattered. The tub is in her cage so even if she escapes it, she will only make it into her old tank. Any tips on how many holes to drill or if I have a sufficient enough. Please and thank you for all the help.



holes in my 12 qt tubs and it works great for me! I think you'll be just fine with 22 but if you find you can't maintain a good humidity you may want to cover up some of the holes.
