I saw a flowerhorn fish in a shop that I frequently go to. I thought it was just a plastic/toy fish but the shop keeper told me that it's a real fish!!! It's super cute and I really want one.

Is it high maintenance? Also, why do prices differ so much at sulit (100, 500, 2500 and even 12,000!) What trait makes it most lucky (color, shape ?) If anyone one has one, please post a picture
