So happy to see that the QT is almost up and running. With it, you will finally have a nice healthy stock of fish in your display. Ching are you concerned that any residual disease or parasites are still in the main display and could possibly infect newly introduced fish in the future? I am unsure of the amount of time these parasites "diseases can stay in a display without a host? Any ideas? Also if there are any fish still left in the display, is there a possibilty that the fish still hold the "disease" but shows no signs of the illness but can still pass the infection onto new fish introduced? i have always wondered for example, how long ich can stay in a tank with no fish and still live without a host? Because I too have had a display wiped out by disease and wondered how long to wait until I could add fish again. thanks, T
