  • Mottled Black: Irregular black patches creating a unique appearance.

Each Koi Angelfish has a distinct pattern of these colors, which contribute to its elegance and the intricate markings on its body.

Body Shape and Size

We recognize Koi Angelfish by their distinctive Pterophyllum Scalare lineage, which is a species of freshwater angelfish. They sport a:

  • Body Shape: Laterally compressed, roughly triangular body enabling graceful movements.
  • Size: Generally reaching about 6 inches in length.
  • Fins: Long and flowing fins are a hallmark of their elegant appearance.

Koi Angelfish are not exceptionally large fish, but their fin extensions and vertical shape can make them seem larger than they are, and provide a stately presence in any freshwater aquarium.

Tank Requirements

In setting up a tank for Koi Angelfish, we need to consider the specific habitat parameters these fish require to thrive, from the minimum tank size to the water conditions.

Aquarium Setup

The Minimum Tank Size for Koi Angelfish should be at least 20 gallons for a pair, but for a community, we recommend starting with a 55-gallon tank or larger. This allows sufficient space for swimming and territory establishment. The interior should mimic their natural environment with Substrate consisting of fine sand or smooth gravel, Driftwood for hiding spaces, and Live Plants such as Amazon swords and Java fern to provide a natural feel. Lighting should be moderate, mimicking a shaded tropical environment, whereas Filtration systems need to ensure clean water and a Moderate Water Flow to reflect their natural habitat without generating overly strong currents that can stress the fish.

Water Parameters

Our Koi Angelfish require:

  • Water Temperature: Kept consistently between 76°F to 86°F, necessitating a reliable Heater.
  • pH: Slightly acidic to neutral; ideally, between 6.8 and 7.8.
  • Water Hardness: Ideally maintained between 3-8 dGH for softer conditions.
  • Our aim is for Water Quality to remain high, with ammonia and nitrate levels close to zero, achievable through regular water changes. The presence of Vegetation and in particular Floating Plants can assist in maintaining water quality while also providing the fish with shelter.

By focusing on these elements, we can provide our Koi Angelfish with an environment conducive to good health and vibrant coloration.

Diet and Feeding

Our Koi Angelfish require a well-balanced diet to maintain optimal health. As omnivores, they benefit from a varied diet that includes both plant and animal matter. We ensure their nutritional needs are met by providing a mix of high-quality flake and pellet foods as the base of their diet.

Daily Routine:

  • Morning and Evening: Feed small amounts that they can consume in three minutes to prevent overfeeding and ensure water quality.

Primary Diet:

  • Flakes and Pellets: Formulated flakes and pellets should constitute the bulk of their diet. They are specifically crafted to provide the necessary nutrients and are convenient to use.

Supplemental Foods:
We occasionally supplement their diet with frozen or live foods to provide variety and additional nutrition. Our choices often include:

  • Tubifex Worms: High in protein but should be given sparingly to avoid fat buildup.
  • Blood Worms: A favorite among Koi Angelfish, these are ideal for occasional treats.
  • Frozen Foods: We include high-quality frozen foods that are free from parasites and pathogens.

Pro Tip: Alternate between food types to provide a balanced diet and keep the angelfish engaged and interested in their food. This practice also minimizes the risk of nutritional deficiencies.

By adhering to these feeding practices, we promote the health and longevity of our Koi Angelfish, ensuring they thrive in their aquatic environment.
