Hello people! I bought a yellow tang and a purple tang on Saturday, I don’t have a QT in place so I know that’s the start of the problem, however they were dripped and acclimated correctly, Sunday I noticed white spots, I immediately went to my LFs, and got some polyp lab medic, and got my uv up and running Monday the yellow tang looked bad I knew what I was dealing with, Tuesday not as meny Visible spots but didn’t eat that day, this morning I checked the tank and low and behold it was dead, I understand the life cycle of white spot and how it affects the fish ect, but have I bought a bad fish in the first place? After only 3-4 days it’s contracted it, or already had it and died? Can it take so little time to kill the fish?
