A separate breeding tank, specifically designed for breeding purposes, is recommended to provide optimal conditions and control the breeding process.

Identification of breeding-ready fish

Before attempting to breed Celestial Eye Goldfish, it is important to ensure you have mature and sexually mature individuals. Males will exhibit small white breeding tubercles on their gill plates and pectoral fins during the breeding season, while females will have a rounder and fuller belly. Monitoring their behavior and physical characteristics can help determine their readiness for breeding.

Spawning process

The breeding process of Celestial Eye Goldfish begins with courtship behavior, where males chase and nudge females in an attempt to entice them to release eggs. Once the female is ready to spawn, she will lay her eggs on submerged plants or other spawning mops within the breeding tank. The male will then fertilize the eggs by releasing milt, triggering the development of the embryos.

After spawning, it is crucial to remove the adult fish from the breeding tank to prevent them from consuming the eggs. The eggs will hatch in approximately four to seven days, depending on water temperature and conditions.

Care for the fry

Once the fry hatch, it is important to provide them with suitable conditions and appropriate nutrition for their growth and development. Infusoria and commercially available liquid fry food can be used as initial food sources. As the fry grow, their diet can be gradually transitioned to finely crushed flakes or pellets.

Regular water changes and careful monitoring of water quality are crucial during this sensitive stage. Proper filtration and aeration should be provided to maintain optimal water conditions. As the fry grow, they can be gradually separated into larger tanks to accommodate their increasing size.

Common Health Issues

Swim bladder disorders

One common health issue that can affect Celestial Eye Goldfish, like many other goldfish varieties, is swim bladder disorder. This disorder affects the fish’s swim bladder, a gas-filled organ located in their abdomen that helps control buoyancy. When the swim bladder malfunctions, the fish may have difficulty swimming upright or may float uncontrollably.

To prevent swim bladder disorder, it is important to maintain proper water quality and avoid overfeeding. Feeding a well-balanced diet and ensuring the fish do not gulp air while eating can also help prevent this condition. If swim bladder disorder occurs, consult a veterinarian with experience in aquatic medicine who can provide appropriate treatment options.

Eye problems

Due to their unique eye structure, Celestial Eye Goldfish are prone to eye-related issues. Common problems include eye infections, cloudiness, or external injuries. These issues can be caused by poor water quality, rough tank decorations, or aggressive tankmates.
