It's really bugging me because I'm SURE I read that about one of the tangs. My trouble is I've looked a ten thousand different sites and now I can't find it!
After thinking about, I'm pretty sure it was either the hippo or the powder blue tang. Literally, one of the sites had an NG beside of it, and the reason was just as I said above.
Honest, I wouldn't put it on there if I hadn't heard of it. Now I'm on a mission.
P.S. Don't I know that wrasses do it! Mine gave me a mild heart attack when I was changing out my cc on Monday!
