Dragons are one of the most beautiful fish in todays market. They are very slim and hard to find, and when you do expect to pay from $10,000-25,000USD.
If you want to keep one or a pair you will need a tank...
10ftx4ftx4ft in size. This is because they need a vast amount of space, some people think that they dont being related to the seahorse but if I am personally doing this and spending up to 25k per fish?
Secondly a BIG chiller, you need to keep a constant temperature.
LR and LS... they need to be pest free.
tank mates - woudnt risk it
Getting them into the country. CITES, MAF and mayby IMER permission. LOTS of paper work
paper work = Money
Lastly feeding, we dont have the same live foods offered in many other countries, so you would have to spend $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ trying to get food for them...
Other than that they are a lovly fish and would be a pleasure to keep.
