I have never had one, nor would I pay a whopping 5000+ for one that will probably die. I have heard they are very hard to keep alive, and are very picky eaters.
a better question is where to get one and how to pay for it
and these fish don't react very we'll to shiping so really you need to catch them form the wild plus not much is know so if oyu do get one and keep it alive please keep i gernal or something seriously these fish amazing and so little is know about them
