Rare corals which have never been sold in Singapore are a bit difficult for the LFS to bring in as they really have no idea whether they will be able to sell or whether they will be stuck with the coral for eternity...
Secondly, the rare corals are usually very expensive and unless a reefer is willing to pay upfront for the coral, I do not think that the LFS would be willing to ship in 1 or 2 pieces just to test the market.
End of the day, I think the only way to move forward will be that reefers start to ask their LFSes to bring in these rare corals and showcase these corals to the rest of the community here. But we will require reefers with deep pockets to kick start this process and in due time, when there is demand for these corals, our LFS may then bring these in on a more regular basis.
