I did not. I probably should dip every new coral. I found this while looking into it. http://www.xtalworld.com/Aquarium/hitchfaq.htm
It looks like they aren't bad necessarily, just ugly. I may pick up a dip next time I'm at my LFS
. The coral doesn't seem bothered but I don't want them to stay. What is a good product? I have only heard of coral RX.
I will make sure to treat all new arrivals.
