Yeah. I got the 10 gallon without the lid, because my boyfriends dad had two 10 gallon lights. Then my boyfriend cut two pieces of wood to cover up most of the other room so there was only space for me to put food in, but enough for air. So I got one 10 gallon for free and paid 14 for the other and got a light and cover for free. I got lucky there. Too bad bettas are jumpers. If they weren't then they wouldn't need tops and could have all the air they wanted for breathing.
Aww well, I love my babies and I'll do whatever I have to to keep them happy. lol.
Sorry for rambling, lol
