I would never buy one (I don't like it, I can't afford it and I would suffer a heart attack if one morning I find it on the floor, like happens to me sometimes with my cheap fish
) but it isn't so surprising to me. People pay this and much more for some 'special' dogs, cats, pigeons, snakes, parrots, etc. IMO there is always a luxury market for luxury customers, and the limit of what can be considered luxury is very different depending on each one. I have 2 small tanks, most of the equipment is second hand, DIY and no expensive brands... But when I look at them and calculate how much money I have spent on them, it looks to me that someone can easily consider a luxury to waste, let's say 800 euros in glass cubes, equipment and aquatic plants.
Even if you can afford it, the point is to feel good with what you do and have.... So, again IMO the question is: will you feel better with this fish at home? Not me, I can imagine a thousand of pretty cheap things that would make me much much happier right now.
