If you follow the thread posted by Stratos, please read the post by Wayne of Riverfront Aquariums from Calgary. I'm the marketing exec from Pang Long, you can write to me at sales@panglong.com.sg
Dreamfish is another top rate company to consider, though they may already have a supplier where you are located. Check out a few fish in a shipment that just landed here (video links in last post of the thread):
Go to cartimar and see if you can work out a deal. Much better to deal in person as without a big order I doubt you will get a big discount. Lots of merlion there to look at and maybe get a deal on.
