I already flushed him. I had no idea they could do that. I tried to see if I could easily remove it but those bumps were on there pretty good. I didn't want to take a chance and have some nasty aliens crawling out of my trash can and attacking me. Especially after looking at pictures of isopods that can live on the fish.
Sorry to hear about the your tang. With a FD some of those, if it was flukes, should have fell off and stayed in the bucket. Keep an eye on the other fish.
