Welcome to PC, you mentioned you have two tanks, the QT (good to see that you're starting out on the right track), what tank are the sterbai cories in. The 125 litre could house some more of the sterbai cories, depending on your stocking plans and whether you are saving up room for other planned ...

Hello from Hong Kong.
