If you have a spare few thousand dollars, why not treat yourself to the Rolls-Royce of fish? That’s if you can even find one to buy. The Peppermint Angelfish is very rare and prices as high as $30000 have been bandied around in the past. Inhibiting tropical reefs by the Cook Islands, this little fish is rather shy and prefers deep water (hence it’s rarity). If you do find one, then you can marvel at its exquisite beauty – the “peppermint” red and white stripes are really striking.
