Hello All So, I talked my parents into letting me get a fish, but I have to pay for it. The problem is that I'm a 16 year old high schooler with a limited income and I also have to save for other stuff. I was just looking to get a smaller tank for 1 betta without spending a ton of money if possible. I have read that round fish bowls aren't that best and I wasn't sure how to start off. Is a 2 gallon tank large enough? Do I for sure need a filter or heater? Once again, I do have a limited amount of money to spend on this so that is the problem here. Thanks for reading.
