Yes, rare and expensive fish that remain rare and expensive are that way for specific reasons. So yes, they are rare because not many can keep them alive because of basic reasons (I.E. Eating habits). So if you are up to a challenge, do what research you can, and give it a shot!
Good luck with your endeavour, I hope I'll get to see those fish.
May I inquire as to what fish you are referring to?
