They are a very beautiful fish but are very very hard to keep alive. They need to be in a well covered tank to prevent escape but when you cover your tank with out air circulation it messes up the ph. Feeding is another issue getting them to eat a healthy diet in captivity gets expensive because they do best with live food and not only things like feeder fish.
Myself I would pass on it from the research I have done. I don't want to take a beautiful creature and watch it die.
