I like bettas, but one betta for a 20 gallon tank might be too big. But I don't know any fish that can go with bettas. I don't know the pH, temp., and what it eats. I had bettas before but they did not survive long. I also heard that strong filters can kill bettas. So it could help if you gave me a brand of filter.Thanks!
