There are currently 3 species of seadragon (
Phycodures) recognised - the weedy, the ribbon and the leafy.
The weedy is probably the most common, and at the moment there is a commercial seahorse breeder who has 5 of them, with the view to propogation for the aquarium trade. It is a very cold water species (16C).
The leafy is the spectacular floating piece of seaweed, graveful and elegant. Extremely vulnerable and protected by our laws, as stated previously. Also from very cold waters. The same breeder will be attempting them next.
The ribboned comes from northern waters, and is therefore tropical. It looks sort of like an in-between of the other two, kinda like a grunge dragon! Very very cool. No one has them, to my knowledge, just yet, although the breeder mentioned before has just got a permit for collection.
Dragons need extremely large tanks as they grow quite large: at least 6ft deep, 8ft x 8ft would be adequate. Also a heavy duty chiller for the first two species. As any specimens would be WC, I imagine some sort of import permit would be required. They eat very small live foods (BBS doesn't quite do the trick) and they eat a lot.
Wait several years, in the meatime get seahorses & learn all you can about sygnathidae. They are a remarkable fish
