I just got a $10 1-gallon acrylic tank for one of my bettas. It came with the little UGF system you've probably seen, but I didn't plan on using it. There are two small holes in the hood - one for feeding and one for the air line tube. It just occurred to me that even though bettas gulp their air, he may not get access to enough (any?) oxygen with only the two holes. I was hoping to keep things simple so if it is indeed to little oxygen, maybe I can just stick the air line tubing in the water a little bit to give it some air... but that doesn't make much sense, either, if he isn't getting air from the water anyway.
Help?
