Give each line a clear home
Separate aquariums are the simplest way to keep breeding groups distinct. Label tanks with the line name and avoid relying on color alone to identify animals.
If tank space is limited, define which colony is a display group and which is a breeding project. Do not call a mixed colony a pure line.
Control equipment transfers
Nets, siphons, and containers can move tiny shrimp or eggs between tanks. Inspect equipment and use a consistent order when working across multiple colonies.
Keep dedicated tools where practical and rinse them in a way that does not introduce chemicals or untreated water. Small juveniles can be hard to spot.
Record every movement
Note when shrimp are added, removed, or transferred. This makes later lineage claims more honest if a possible mix-up occurs.
If lines do mix, document the event and treat descendants as mixed or uncertain rather than hiding the change.
