I have a 350g bare-bottom FO. The last additions to the tank were a Koran angel and an Atlantic Blue tang during the first week in December. Both fish were QT'd for 6 weeks with no issues.
Prior to that I added some live rock from NYA a month earlier (also qt'd).
Now I have noticed that a few fish were twitching and sure enough I see some light cases of ick breaking out. How is this possible? I had always been a believer that Ick is not always present in a tank. I guess I am wrong.
How on earth do the parasites go that long without manifesting themselves? Especially in a bare bottom system. What a huge PITA it is going to be to hypo a 350g tank. That is a lot of water.
Anyone else ever have Ick "spontaneously appear"?
