Hello. As title said, is there any solid way/test to tell if my tank is infested with ich or not?
Background: My DT had an ich outbreak before, I left tank fallow for 77 days but did add corals frags & snails (from multiple sources, no qt) in between. All fish (a pair of clown, potters angel, and melanurus wrasse) had been through TTM/Prazipro followed by an observation period in QT while the tank in fallow, no signs of disease observed. After the fallow period, I re-introduced the fish back to the DT. About 2 weeks ago, I saw one of my clown scratched its head/mouth against rock and a few days later I saw the potter's angel did the same thing. I did spot one or two very fine/tiny flat white dots on the angel and one raised white spot on the clownfish's anal fin. Those spot cleared up in a day and that's pretty much of the scratching/flashing/white spots I have witnessed so far, I have yet to see any since. I'd love to know if there's a way to tell for sure if ich is still lurking around before adding more fish into the DT.
Btw, last week my angel had a whitish/brownish stingy poop and today my clown had a white stingy thing too (but the angel ate it when the clownfish finished her business so I'm not sure if it's poop or not). I really hope I'm overthinking.
Thank you.
