The best places to get Parrot Cichlids is at either a specialty exotic fish store, because they will probably happy to order what ever fish you want if they don't currently have it. Otherwise try a Petsmart or Petco.
Find another aquatic pet store. If no one in your area carry these fish (as they are a rare breed) then they may need to place a special order for you. Ask them what their policy is on ordering a shipment of this breed.
