Pacific blue-eye Breeding Guide

Breeding Process for Pacific Blue-eye

Pacific blue-eyes are moderately easy to breed in captivity, making them a suitable choice for hobbyists looking to expand their fishkeeping experience. To begin the breeding process, a separate breeding tank is recommended to ensure optimal conditions and protection for the eggs and fry. Set the water temperature between 24°C to 26°C, and maintain a pH level from 7.0 to 8.0 to closely mimic their natural habitat. A tank that holds at least 30 liters is ideal, as it provides enough space for a small group or school to breed successfully. Introduce a group consisting of a higher ratio of females to males, such as one male for every two to three females. This reduces stress and increases the likelihood of successful mating. Provide plenty of live plants, spawning mops, or fine-leaved plants where the females can deposit their eggs. These features also offer shelter and reduce aggression during the spawning phase.

Care of the Fry

After spawning, the male Pacific blue-eye may display mildly territorial behavior but typically poses no considerable threat to the fry. Remove adult fish from the breeding tank once spawning is complete to prevent any risk of egg or fry predation. Eggs will usually hatch within 7 to 10 days, depending on the water temperature. Newly hatched fry are quite small and should be nurtured with infusoria or commercially available liquid fry food until they grow large enough to accept micro worms or finely crushed flake food. As they develop, transitioning to a varied diet including brine shrimp and other suitable fry foods will encourage healthy growth and color enhancement. Regular water changes are essential to maintain water quality, ensuring a conducive environment for the fry to thrive.

Additional Information

Pacific blue-eyes are social and non-aggressive, which makes them an excellent choice for community tanks as well. However, as with most species, their breeding behavior can result in slight increases in aggression. Providing a spacious environment with adequate hiding spaces can help mitigate stress and promote successful breeding. Regular monitoring of water quality, temperature, and pH balance is crucial to the health and development of both the eggs and the fry.
