I’m Pretty sure my tank has either ich or marine velvet. I was careless and purchase fish and added them directly to my tank without quarantining them. A couple days ago I notice White spots on one of my clowns and as the days passed the number of white spots has increased. Another clown displays no white spots whatsoever. These are my only fish. I have done a ton of research and am simply confused about what to do next. My Display tank is 30 gallon. I just purchased 5 gallon tank that I will use as a quarantine tank. I know in order to kill the ich my display tank has to go without fish for 76 days. How should I go about setting up my quarantine tank. My concerned is seeding the tank. I have many small pieces of live rock in the back compartment of my display tank. Can I use this even though it is infested with ich. Should I avoid adding anything from my display tank other than the two clowns? Should I just do water changes every other day? I would not like to do this because of a hassle. I will also be treating the fish with a copper supplement. Is there one in particular that you guys recommend. From now on, I will quarantine all fish before adding them to my display tank.
