I would not recommend one. They are just about one of the most beautiful fish, but very difficult to keep up with. Expensive to maintain. In the wild they eat a copepod every 3-4 seconds. And they are constantly active. You would have to have a refugium, and breed copepods in order to make it a logical fish selection. If I were you, get a nice picture of a mandarin, hang it on your wall, and just admire it from there! Lol
