Watch for repeated leg movement
A berried female may use the small swimmerets beneath her abdomen to move water around the egg cluster. The motion can be subtle and intermittent.
Plants and body angle often hide the eggs or legs, so a short view may not show the full behavior.
Avoid turning movement into a test
Do not shine a bright light, tap the tank, or net the animal to trigger a response. These actions change the conditions and may stress the shrimp.
Normal movement varies among individuals. One quiet observation cannot establish that eggs are healthy or unhealthy.
Use a wider care picture
Keep water stable and provide cover. Record visible behavior alongside the date and any recent maintenance.
If several eggs are lost or the female seems distressed, review the aquarium and seek experienced advice rather than relying on fanning alone.
Use these as general hobby references. Test your aquarium and confirm product guidance before making changes.
