I bought 1 betta today and its living in a 1 gallon aquarium. It currently has oxygen (those bubble thingys lol) but do i really need it?
The aquarium has a top cover but it has 1 opening so air can get in and out and that's where i drop my food at. I heard bettas get oxygen by rising to the surface and getting the air there.
So do I really need it? Cuz if i don't, I would just take it out to save some space.
