Fish Crazy
Going to be getting some kind of freshwater puffer for my new Juwel 180 Litre, the sponges from it have been in my older established Juwel tank for well over a month to colonize them with bacteria, and also Im putting the external filter from my established tank into my puffer tank because I have a new one. With all the benificial bacteria from the sponges and bacteria from my external would it be okay to add a Puffer right away, or still use tester fish for a while??
