So my local Petsmart has the 9 gallon Biube tank on clearance for like $70 and I'm thinking of getting it. I've always liked these tanks but they were always way more than wanted to spend on a tank. Has anyone had experience with the Biube or even the biorb tanks? I was wondering if the filter/air pump has to be used or if it can be taken out. Since I really don't want to have to buy specific plants and decor for this tank. It would house just 1 male betts with regular water changes. The videos I've seen make the air pump lookmlike the top of the water is too much for a betta. Anyway just looking for a little advice before I go out and buy it. Thanks!
