Use this setup as a Pelvicachromis pulcher spawning guide to ensure you get the healthiest and best-looking Kribs fry. 

The female rainbow kribs lay up to 100 eggs, which the males then fertilize externally. The parents guard their young and provide oxygen by fanning them within the first 2-3 days before the eggs hatch. 

After hatching, the fry will become free-swimming in 5-6 days. 

Fry Care Tips 

Feeding, housing, and protection are the basis of raising cichlid fry. Start with infusoria and finely crushed cichlid fry food. As they grow, separate the stronger fry from the weaker ones to prevent bullying and predation. 

Once your pets are mature, healthy, and ready to join the main tank, quarantine them for a few days before including them to the community.
