Genetically double dose halfblack, these angelfish are "unturned", meaning they are not currently expressing the halfblack pattern like the fish in the picture. Many will "turn" at a later date given favorable environmental conditions. Some will never turn, but carry the double dose of halfblack and will pass it along to future generations. Half the fish are ghost and half silver. Single dose blue. Fish are standard fin. We cull agressively to avoid bent fins, gill plate problems, etc. We stand behind the affordability and health of our angelfish. Angelfish are approximately (+/-) dime size, they are 5-8 weeks old. Freshwater angelfish. Disease-free. Live arrival guaranteed. We highly recommend use of our Golden Pearls food and our Miracle Mini Bites food for our angelfish, as it is what they are used to eating.
