How to Care for Your Red Cap Oranda

The red cap oranda (Carassius auratus auratus) is a type of goldfish. Its body is covered in iridescent white scales, its tail is long, flowing and split, and its sports a fleshy red cap, or hood. They are slightly egg-shaped and generally more rounded than the average goldfish. Like goldfish, they are native to Asia, where they inhabit slow-moving and stagnant waters of rivers, lakes and ponds. These fish generally grow up to 6 or 7 inches long in captivity.

Instructions

    • 1

      Outfit a 30-gallon tank for your red cap oranda, as these fish need lots of oxygen and space.

    • 2

      Line the tank bottom with a layer of gravel substrate.

    • 3

      Provide a system for the tank that will constantly filter the water.

    • 4

      Change up to one-third of the water once a week.

    • 5

      Provide shelter in the way of tank decorations and plants, such as smooth rocks, driftwood and plastic or live plants. Include a light in the lid of the tank if you choose live plants.

    • 6

      Feed red cap orandas a high-quality flake food daily, one made specifically for goldfish. Follow the label instructions for dosage.

    • 7

      Choose freeze-dried foods over fresh ones, which can transmit bacteria and parasites that can lead to infections.
