Just curious - do you have a person watching the tank? If not - that would be a good idea - if your fish do die -it's possible you may have an ammonia problem in addition to the rest.So update before I leave for work again. The tang was looking really bad this morning and died off before I left so I could take it out to prevent some of the parasites. One of the clowns start to look spotty now as well but the rest of the fishes still look spot free. So I’ll update on everything when I get back from this trip. Best case scenario I have some fishes I can save when I get back. And start a new quarantine and medication for them.
