So my 72 day waiting time finally up. but im scared to release my fish into display tank. After seing some spots on them that look possible like ich. here is what happened 3 week ago i got 75 gallon tank due to the 50 gallon bin i had the fish in started to leak. so i transferred all my fish to it. After transferred all my fish i was able to observe them better. just to find some brown/yellow spots on them, and blonde naso tang had a brown patch by his gill, Purple tang was stressed out, and powder blue tang had yellow spots on fins.
During this whole time i had constant battle with high ammonia then high nitrites. Until 2 weeks ago i did 75% water change and i used water from my main tank this time. (fallow period was up already) So ever since that time about 4 day later all fish looked good. brown spots were gone.
So I think almost 10 days have passed now and my fish look good so far. but still im scared to know if i still got ich on them.
I was pretty confident I did my ttm properly
