Hey Everyone, I have a 75 gallon tank and a 20 gallon quarantine tank below/growout fry tank. I was thinking when i purchase new fish and quarantine them should I add any medicine for preventive measure or simply just observe them for a month with out medications before adding to display? Also what medicines do you think I should purchase to have on hand always? I was thinking so far Prazipro, API Aquarium Salt and ICH X. Would this cover pretty much most diseases I would come across or should I add more?
