Choose a workable level of detail
In a shared colony, individual parentage may be impossible to know. You can still record the tank, color line, dates, and which adults were present.
Use stable IDs or photographs only when animals can be distinguished reliably. Do not assign a precise parent pair based on color alone.
Track changes over generations
Record which animals were selected or moved and how the offspring appeared under consistent lighting. Keep observations separate from expectations.
If multiple lines share an aquarium, note that mixing can make ancestry uncertain. A dedicated breeding tank is easier to document.
Report uncertainty clearly
When sharing results, say whether parentage is known, probable, or unknown. This helps other keepers understand the limits of the observation.
Records improve decisions but do not create guaranteed genetics. Keep environmental conditions and selection criteria alongside the lineage notes.
