There are few sellers like me in the hobby, who are dealing exclusively in marine life here in the north. Yes the stock becomes little expensive due to the air freight. Live rock direct from the ocean is not advisable as its bad for the environment and the tank in a longer run, but cultivated rock is available now and then. If you are looking for rock which has that purple line algae you can grow that yourself by dosing cal and iod in the marine tank. Well corals is a debatable topic so will not touch that. Beggars can't be choosers, everything is based on the divers what they are able to catch and its not easy. Sometime catching a single damselfish in our home aquarium with rock scape is next to impossible. This and being in a land lock geography makes it very difficult to get the complete selection of marine life in the north.
