Mini carpet anemones might be all the rage right now... or did that trend pass also?
Eckreef: It seems that there are waves (no pun intended) of popularity for corals, and during that time their price goes way up. Bright colored zoas, acans, duncans, chalices, mini carpets... they all had their times where they were the "new" hot thing to collect and have.
* Note: I will say that I have some of each of the above, minus the chalice, just not when they were crazy expensive.
