I’m not sure if my fish have ich or velvet. I made a bad call on a copper band butterfly. He was in the tank for two days and I seen spots develop. Four days later other fish got white spots. All the fish went into QT with copper for 2 weeks and now into an observation tank for 21 days all fish are happy and no white spots. Today is six weeks fallow. Last week I did a rip clean of the DT 100% new water and rinsed the sand. While is was cleaning the DT I setup a new 55 gallon tank to hold the rocks, corals and inverts. So my question is if I put one fish in the tank that had the rocks for two weeks will that tell me if I have the 76 day strand of ich? Or will that strand only be in the free swing stage at like 74 days? Is it worth the risk of moving a fish to the 55 that had the rocks with whits spot disease?
