Pick criteria you can see
You might compare coverage, opacity, or pattern separately. Avoid adding vague categories that different keepers interpret differently.
Define each score in plain language and note the lighting conditions used for evaluation.
Leave room for unknowns
Use “not observed” when a shrimp is too small or hidden. Do not force a grade when the evidence is unclear.
Keep age and photo quality alongside the trait record, because both affect visual comparison.
Use the matrix as a tool
A simple table can help you compare groups and decide which animals to retain for breeding. It should not become a universal commercial standard.
Review whether the criteria still fit your goal after each generation, and record any changes to the method.
Use these as general hobby references. Test your aquarium and confirm product guidance before making changes.
