I would consider the black cap but they are literally impossible to find in my state (Hawaii). Orchids are occasionally available at my local petcos for $30. To find a Royal Gramma I would probably have to go to Coral Fish Hawaii or Tropical Fish Hawaii this is the main supplier for most fish found in Hawaii that are sold in stores around the world. They are extremely cheap and sale every thing from Achilles tangs for $25, Yellow, Chloe and PURPLE Tangs for only $14, Potters Angels for $20, Potters Wrasse for $9, Flame / Coral Beauty and Lemon Peal Angels all for only $25. Crazy right. They usually get a Philippensis shipment ounce a month and get Royal Grammas $20, Mandarin Dragnets $15 and tons more.
