I am getting ready to move my 9 red bellies to a larger tank. I found a 125g tank for a preatty good price. Wanted to check to make sure 9 reds will have enough room fully grown? I could also just hold out for a 150g, but im not sure when that could become available. I really dont want to get ride of any of my red's. Is 125 going to be enough room for 9 reds to become fully grown?
