A hardy shoal still deserves an arrival page
White cloud mountain minnows are forgiving fish, which is exactly why their records get skipped until something goes wrong. On day one, write how many arrived, their source, and whether they are the standard form or a golden or long-finned variety. Photograph the shoal against the glass, noting the red tail and dorsal edges and the pale stripe along the flank, and flag any fish that is thin, faded, or missing fins. Record the tank they entered and its other inhabitants. That baseline matters later, because a slow decline in a hardy species usually has a long history that only written notes can reconstruct.
Cool water is the number that defines this file
The temperature section leads a white cloud record, because these minnows come from cool mountain streams and thrive in unheated water that would chill tropical fish. Log tank temperature morning and evening for the first fortnight, and note the room's swings, any window sun on the tank, and the absence or presence of a heater explicitly so a future keeper does not add one by assumption. A warm spell pushing the tank high for weeks is a health factor for this species, and only dated readings show it. Add pH, ammonia, nitrite, and nitrate on the same rhythm, plus flow, since a gentle current suits them.
Shoal behaviour and tank-mate entries
Note how the white cloud shoal spreads through the upper and middle water, whether males display to each other with flared fins, and whether the group stays bold at feeding or retreats when larger tank mates move. List every companion species and its size, because placid minnows can be quietly outcompeted or, in the case of tiny fry and shrimp, become hunters themselves. Record any spawning behaviour — these fish scatter eggs among fine plants or mops — and whether eggs or fry were moved. Dated entries for additions and losses keep the shoal count honest, which matters when breeding or rehoming decisions depend on it.
Feeding notes for small, cool-water appetites
Write down the staple food type and size, any live or frozen treats, and how feeding frequency matches the cooler water: appetites and growth run slower at lower temperatures, and uneaten food lingers as a water-quality risk. Log which foods are taken eagerly and which sink ignored, and note body condition across the shoal each month — a gradual thinning in a few fish while others stay round points to competition rather than a tank-wide problem. If the whole shoal refuses food, gasps at the surface despite cool water, or shows rapid breathing, test immediately and seek aquatic veterinary advice, bringing the temperature history with you.
Keeping a simple file that outlasts the first tank
White clouds often begin as a first fish and end up in a larger community, a pond-style setup, or a friend's tank, so keep the records in one backed-up place from the start. Include the equipment list, the unheated temperature pattern across seasons, and a sitter note explaining that a cool, quiet tank is correct for this species rather than a fault to fix. Update the count and varieties whenever the shoal changes. Storing the minnow history in KinsLe through a Pet Passport keeps those records together in one portable packet, ready for a vet visit, a seasonal move, or a handover.
