Oh well takes 3-4 days to hatch, n they'll be 7-8 days old before yoke saks are dry n they eat brine shimp. It takes 24-36 hours to hatch brine so you'll need atleast 2 hatcheries.they'll eat brine for a good week, then bloodworms, brine shrimp, flakes, baby bites,ect. Methylene blue in with eggs will help prevent fungus n help you have stronger healthier fry. Keep me posted. Mine are spawning tonight too!
