When ruby fish have spawned, here are some common handling steps and suggestions:
1. Transfer the eggs: After the ruby fish spawns, it is usually recommended to transfer the eggs to a separate hatchery or breeding tank. This provides better protection and control of the breeding environment, improving the survival rate of juvenile fish.
2. Maintain water quality: Ensure that the water quality of the transferred hatchery or breeding tank is suitable and similar to the water quality of the ruby fish before breeding. Maintain appropriate water temperature, water quality, pH and hardness to promote hatching of eggs and healthy growth of young fish.
3. Provide proper care: Ruby fish eggs often require specific conditions to hatch successfully. Understand, based on experience and literature, the conditions required for a particular species of ruby roe, such as temperature, light, water flow, and oxygen levels. Providing the right conditions can help eggs hatch and the development of young fish after hatching.
4. Observation and Cleaning: Closely observe the eggs as they hatch. Some ruby fish eggs may take a while to hatch, depending on the species and specific conditions. Check the health of your eggs regularly and look for necrotic or moldy eggs. If unhealthy eggs are found, they can be carefully removed to prevent the spread of disease.
5. Feed and care for baby fish: Once the eggs hatch, baby ruby fish will emerge. During the first few days after hatching, the young may rely on the yolk sac for nutritional supply. As they grow, you can begin to gradually add appropriately sized spirulina, ground dry food, or specialized juvenile fish feed. Make sure to provide appropriate feed and appropriately sized pellets to meet the nutritional needs of your young fish.
Please note that the process of spawning and raising ruby fish requires some experience and expertise. If you have questions about handling ruby fish eggs and juveniles, it is recommended to consult an experienced farmer, professional fish store or join a relevant fish forum for more specific and accurate guidance.
