Create an egg refuge
Use mesh, marbles or dense spawning media that allows eggs to fall away from adults without trapping fish.
Use mature clean water
Eggs and larvae are sensitive to waste. The spawning tank should be cycled or supported by mature gentle filtration before use.
Remove adults promptly
Observe the event and transfer adults once spawning is complete. Do not leave them hoping they will ignore the eggs.
Match light to the species
Some eggs are sensitive to bright light. Use species-specific information rather than making every spawning tank dark.
Prepare microscopic foods
Many egg-scatterer fry are smaller than livebearer fry. First-food readiness determines whether a successful hatch becomes a successful brood.
