Ok so I finally have my new upgraded 250L tank up and running with all the fish from my old tank now installed. New external filter for the new tank was seeded in the old tank and left running in the mature tank for a couple of months before the big move yesterday.
So obvioulsy I now want to add more fish. Im pretty sure i have to do this gradually, so how many at a time and how long in between please?
