im getting a male betta fish. the tank is from 4-5 gallons and i will have a filter and 2 fake plants in it 1 plant which is small the other which is exeptionally big. im definatly keeping the same tank size, plants and filter and gravel and betta. i want to know if their are other fish that can live with betta fish without them fighting. i once had a ctafish with my old betta and my betta chased it all the time it was great workout for my betta but my catfish then spent all his time hiding in the filter. i want to know if their is fish that this wont happen 2!!!
