The weekly entries a cherry shrimp colony needs
A cherry shrimp diary works at colony level, not individual level. Each week, record temperature, pH, and — because shrimp depend on minerals for their shells — hardness readings if your kit provides them, alongside ammonia, nitrite, and nitrate. Note the size of the water change and exactly how the replacement water was prepared and matched, since shrimp tolerate steady conditions far better than sudden correction. Add the staple food offered, any mineral or leaf additions, and one line on grazing activity: a colony spread across the plants and glass is behaving very differently from one clustered motionless near the filter outflow.
Molts, berried females, and the running count
Cherry shrimp progress is counted in molts and babies, so the weekly diary needs a reproduction section. Record empty molt shells seen, any females carrying eggs under the tail — berried females — with the date first noticed, and the first sighting of tiny shrimplets roughly three to four weeks later. Keep a rough headcount by photographing one side of the tank and counting from the photo, accepting it is an estimate. Note deaths as numbers too, including any shrimp found with a pale ring around the midsection, which keepers associate with a failed molt. These dated lines turn a vague sense that the colony is shrinking into a measurable trend.
Change entries: the shrimp diary's detective pages
Shrimp losses usually follow a change, so log every change the week it happens: a new plant and whether it was rinsed or quarantined, a different water source or conditioner routine, a fresh stone or wood piece, a medication used anywhere in the tank for fish, or a deep clean that disturbed the substrate. Note fertiliser or algae treatment use in planted setups with special care. When a die-off begins, this section is where the answer most often sits — a dated entry showing a plant added two days before deaths started is worth more than a week of water tests after the fact, though those tests should still be run and recorded.
How long to keep cherry shrimp entries
Keep the diary for the entire life of the colony, which can run for years and many generations, and review older entries whenever you repeat a routine — a preparation method that preceded losses once should not be rediscovered by accident. The last two to three months guide weekly care, but the full history is what reveals slow drift: hardness creeping as top-ups replace changes, breeding pausing each warm season, or deaths clustering after one particular product is used. Because entries are short, nothing is gained by deleting them, and the earliest pages hold the original conditions under which the colony first thrived.
Acting on the diary and keeping it in one place
Treat a week with multiple deaths, failed molts, and a silent, clustered colony as an instruction to test everything, pause non-essential additions, and seek advice from an experienced shrimp keeper or aquatic vet, diary in hand. Keep the whole record — water lines, reproduction counts, and change log — together and backed up, with a sitter note explaining that small, steady changes beat large corrections for shrimp. Maintaining that diary in KinsLe as a Pet Passport keeps the colony's records together in one portable packet, ready for advice, a tank move, or passing the colony to a new keeper.
