I bought a 2nd Betta and I’m going to be putting both bettas in a divided 10G after new Betta is out of QT. I will be moving their filters over to the new tank for an automatic cycle. Should I: 1). Go ahead and transfer the fish at that time using a little Prime and just test in a few hours to be sure the tank cycled? 2) Leave them in their cycled individual tanks with no filter but with an air stone for a few hours until I know the new tank cycled. Suggestions?
