We recently bought a 60 gallon tank and we put in a combination of koi and golfish-9 total. We bought the tank about a week and a half ago. We let the tank sit for two days before adding the fish in and just today, we noticed they were rubbing themselves on the gravel. What's wrong with them and what can we do to help the fish?
What's double filtration? All I know is that we have a biowheel and this weird flossy blue thing that the water runs through.
