To maintain these water parameters, it’s important to change 10-20% of the water per gallon regularly.

Tank Maintenance

To maintain high water quality for Dragon Eye goldfish, perform weekly water changes of up to 30% of the tank volume. Use an aquarium vacuum to remove organic waste and detritus from the substrate, focusing on areas under the filter box and in the corners.

A minimum tank size of 20 gallons is preferred for these goldfish, but at least 10 gallons is required for young ones. Choose smooth decorations to protect the fish’s eyes.

Introducing hardy live plants can improve water quality by providing oxygen and absorbing nitrates, although Dragon Eye goldfish might eat or uproot them.

Common Diseases

Maintaining a Dragon Eye goldfish’s health requires attention to prevent common diseases such as fin rot, ich, and swim bladder disorders. These fish, related to Black Moor and Telescope goldfish, are prone to certain conditions due to their unique shapes and features. Proper care includes:

  • Monitoring water quality and temperature consistently to prevent diseases like fin rot and ich, which is especially important for Dragon Eye goldfish, a type of Prussian carp.
  • Providing a balanced diet and following quarantine procedures to reduce overfeeding and digestive problems, as well as to prevent the spread of diseases among fish.

Use spawning mops during breeding to keep the environment clean and reduce disease risk. Regular checks and immediate treatment are essential to keep your Dragon Eye goldfish healthy.

Temperament Traits

Dragon Eye goldfish are calm, making them good for community aquariums with other non-aggressive fish. They are peaceful and can live with other non-predatory fish. These goldfish are gentle and playful, often chasing each other and interacting with their environment.

They are curious and can recognize their owners, which makes them interactive pets. However, they may nibble on aquarium plants, so it’s best to choose hardy plants.

Keeping Dragon Eye goldfish healthy requires a clean aquarium and a diet of quality pellets and live or frozen foods. They need regular water changes and close monitoring due to their sensitivity to water conditions.

Breeding Dragon Eye goldfish is complex and needs careful planning and a controlled environment to protect the fry. Proper breeding care is important to maintain their calm and engaging nature, similar to fantail goldfish.

Compatible Tank Companions

Dragon Eye goldfish are compatible with Ranchu, Oranda, and Ryukin goldfish due to similar temperaments and care needs. When choosing tank mates, ensure species compatibility for a peaceful main tank environment.

Suitable tank companions for Dragon Eye goldfish include:

  • Goldfish Varieties: Ranchu, Oranda, and Ryukin. These varieties are well-suited to goldfish-specific conditions and require at least 20 gallons of water per fish for sufficient space and water quality.

These species are non-aggressive and share similar water requirements with goldfish. Snails also help maintain tank cleanliness by eating algae and leftover food.

Avoid adding fin-nipping or aggressive fish to prevent harm to the Dragon Eye goldfish’s delicate fins.

Reproduction Practices

To foster a successful breeding environment for Dragon Eye goldfish, aquarists should establish a dedicated 20-gallon spawning tank that emulates their natural habitat, complete with appropriate flora and stable water conditions. The tank should provide numerous surfaces for the goldfish to spawn upon, such as plants or spawning mops. Maintaining a temperature range conducive to spawning behavior is critical, as is ensuring the fish are well-fed with high-quality foods to encourage readiness to spawn.

Dragon Eye goldfish are egg layers and exhibit spawning behaviors when conditions replicate their natural environment. The breeding process should aim to stimulate natural triggers that prompt the fish to reproduce. It is important to note that it is nearly impossible to breed Dragon Eye goldfish before they reach maturity, making it challenging to select breeding pairs. However, once a female is around a male during the breeding season, spawning will usually occur.

After spawning, the female will scatter her eggs over the provided surfaces. At this point, it is essential to need to remove the adult fish from the spawning tank to prevent them from eating the eggs. The eggs will hatch within a few days to a week, depending on the water temperature. Close monitoring is required to safeguard the eggs from fungal infections and other hazards.

Selective breeding is also a significant aspect of propagating Dragon Eye goldfish. Breeders should carefully choose parents that exhibit desirable traits, such as large, prominent eyes, to ensure these characteristics are passed on to the fry. Successfully raising the fry involves transferring them to a separate tank and providing them with appropriate nutrition and water conditions to promote healthy growth into mature, show-quality Dragon Eye goldfish.
