Guys my tank once crashed because of Ich and I lost everything. I cleaned the entire tank out and restarted. I QT my first batch of fish and everything was fine. I got more fish on Thursday and they were put in QT. Someone in my family, put the fish because they looked OK in the main DT today afternoon around 5. I came home just now and saw the Blue tang and blue ring angelfish with white spots on them, the blue tang especially. I also found some spots on my yellow fox face. I immediately took them out and put them back into the QT and put some more ICH medicine. My concern is the main tank, not sure if I’m overthinking or if I see white stuff swimming around to be ICH spores. I increased the temp to 85, it’s at 79 so far. Will I be ok? What should I do? After my crash I’m crap scared, please help me out!!!!
