Know who is the predator
Adults, tank mates, snails and even older siblings may eat eggs or fry. Some parents protect offspring; others consume them.
Separate by method
Remove adults from egg-scatterer tanks, provide plant cover for livebearers, or leave proven parental cichlids when the community is safe.
Make every intake fry-safe
Cover power-filter intakes or use a mature sponge filter. Check gaps around dividers and boxes.
Keep visibility
A protected area that cannot be observed or cleaned may accumulate dead eggs and waste.
Avoid overcrowding
Saving every fry is not humane if the grow-out system cannot support them.
