i would say that the common red and green striped pieces that are 3-4 inches should definetley not cost 250 dollars.
go on ebay hey have very nice sized acan lord pieces everyweek, buy a seller called "instareef" very nice pieces but they cost like 150 bucks.
a red stripped or green stripped should not cost more than 200 dollars if its 3 inches....
to some it all up,,, these are common corals, and contrary to popular belief they are very abundent in indo and non indo water, its just a mater of which government lets them out.
