I have a 2.5 gal aquarium with a single betta in it and i was wondering if anyone knew if it was possible to filter such a small aquarium effectivly? I was going to move him to a bigger tank, but he has a bad temper and kills any fish he sees. I was just wondering if i could filter the tank because all the water changes are getting pretty time consuming. I have to change all the water every 5 days or it starts to smell. I change a small amount of the water every day. I just would like it if i didnt have to change all of the water so often. Any suggestions would be great
Thanks
