Hi people. I'm new to betta keeping (or at least PROPER betta care). I want to add more fish to my tank. I was thinking some Phantom Tetras. I currently have one happy, healthy, male betta fish. His name is Poseidon. He lives in a 10 gal. tank with a heater and filter. I hear that to introduce bettas to a community tank, you put the betta in a breeding container so they get used to each other, then release the betta into the tank. could I do this with 3 Phantom Tetras to put them in Poseidon's tank?
