There are a lot of things like that which I think are overpriced, usually because they grow quickly is my reason. Bubble tip anemones, Kenya trees, montipora caps, acans, Duncan's. Although some fads are to blame, what's hot this year...chalices? Ugh
Divers Den and MyReefToYours. Ill buy acans from Jared anytime, I've been happy with them and he has better priced frags than other places.
