I spoke to the collector/guy who placed them there. He told me 188. The store is just holding them until they are distirbuted. The vast majority going to Asia where they go for $4000+ USD each.
There is a specific permit required to collect them, which only this one guy has. They are SUPER abundant in their native habitat, but since collection is pronibitive without the eprmit, they are rarely seen. I doubt they will be collected for another 10 years after this batch, if ever again.
On a similar note, Clipperton angels may make the market soon. They will be the new angel du jour (which I WONT be buying). They are only found at Clip[perton Island (in the middle of noweher). Dr Bruce Carlson is rather well known for having one of the first in captivity that he took care of perosnally at the Waikiki aquarium.
