Well, if you read the beginnings of a lot of limited edition corals and zoas, most of them are just happy accidents. The Leng Sy cap came on a piece of live rock and didn't look like much until it was given some care. Some of the hitchhikers we get can turn into something great given a little time...just depends on how much patience you have.
When Acans were in vogue the prices were through the roof, now they are much more reasonable in price.
Seems like palys and zoas are the new "IN" thing...hence the out of sight prices....
