Hello! I'm setting up a 20 gal long tank that will have a school of glass catfish. I'm trying to think of another fish that would go well with them I was wondering if a betta would work. They are translucent and very peaceful so I've read that many people have kept them together before. I'm thinking of getting a female betta bc the tank will have a strong filter and she will be able to swim better with the shorter fins. Anyone have experience with the two before? Any thoughts appreciated!
