I have recently moved three of my Bettas into larger tanks, but they didn't come with filters. Filters can be so expensive these days, so I was wondering if anyone knows a good DIY filter I can do, or if someone knows where I can get a filter for cheap. I have a 2 gallon, a three gallon, and a 5 gallon. My Betta in the 2 gallon has a permanent Swim Bladder disorder, and I don't want to make swiming too difficult fo her either. Please Help!
