These guys are fascinating, but unfortunately very rare as well. In the early 1990's In the Australian government declared the leafy sea dragon a totally protected species. They can't be taken or sold. There was a guy somewhere, the only one I've ever read about, and this was a while ago, who did have a breeding pair, but apparently he can only sell them to aquariums (educational purposes) or such and I think the price for each was about $35,000. They are very fragile, are only found in Australia I believe and are from cooler waters.
