HI everyone, 1. When getting new fish and there is NO fish in the tank that they will be housed in, do you still need to quarantine or could you just put them in their new home right away? 2. Can 2 mollies be enough to cycle a 30 gal with established media? 3.If female mollies are seperated from the males so they won't breed,will the females/males/ be okay like this or would they start getting aggressive with their own sex? Thank you all very much!
