@chefjpaul I lost all but 4 fish to velvet and yeah, it's fast. 9 out of 13 in less than a week. I'm doing observation qt for fish. Tried coral qt but was losing them so put them in tank. Tried to QT 2 mandarins and lost them. Got 2 more and they had to go right into the display. I think there are some fish that just don't do well in qt. I'm working toward higher quality foods, some live foods, to build immunity. And going a bit slower in my restocking. Have a goby and 2 clowns in my qt tank now. All eating and acting good. Not sure if I'll treat or not or just observe for another couple weeks. And love your organized closet!!
