That is so true. There are so many painful challenges in this hobby that stubbornness is a required characteristic. I try to focus on the good, learn from the bad. And obviously we get some weird crazy thrill from our aquariums or we would not do it. Lol. Thanks for the encouraging words. I needed it today. I went to check on my blennie in QT and he was on his side breathing hard and fast and pale. The yellow tail damsel? FINE. I must have raised the copper too much. I did a 50% water change. And as the new water came in he improved. I hope I caught it in time. And I hope I did not nuke my biological filter. The ammonia badge was between the yellow and green alert color. I added Stabile and will watch it closely. It does suck about your fish in QT. Yeah it happens but it still sucks.
