A holiday log fails in two ways: the anxious essay that buries the one detail that mattered, and the cheerful blank that proves nothing. The format that works sits between them. One line per visit, six fixed fields, the same order and the same words every time, so the week reads as a steady row of matching lines and any change stands out on sight.
The Six Fields, in Fixed Order
Field one is time: the time of the visit, written the same way each day. Field two is food given/eaten: what food was offered, in the measure you specified on the tank label, and whether it was eaten, part eaten, or left. Field three is fish present: a count against your stock list, written as all present, or naming exactly which fish could not be found.
Field four is water level: level against the mark you have drawn or taped on the glass, written as at the mark, below the mark, or topped up to the mark. Field five is temperature: the thermometer reading, written as the figure itself rather than a judgement, so a slow drift shows across the week. Field six is actions taken: anything the sitter did beyond feeding and looking, such as a top-up, a rinsed pre-filter, or nothing beyond the visit itself, which is a perfectly good entry.
Prepare the log page before you leave, with the six field headings written across the top and one ruled row per planned visit. Beside it, leave the stock list with a clear photograph or description of each fish, the food with its measure marked on the container, and the level mark visible on the glass. The sitter should never have to invent a format or guess a name mid-visit.
A Worked Line, Read Closely
A settled mid-trip line reads like this. Time: evening visit. Food given/eaten: one measure of flake, all eaten within minutes. Fish present: all present against the stock list. Water level: at the mark. Temperature: 25 °C, written exactly as read. Actions taken: none beyond feeding and checking.
Read that line against the line above it and the line below it. With every field in the same place and the same wording, your eye travels down each column in seconds. Temperature figures that creep by a degree a day, a water level that drops faster than evaporation explains, or a food entry that changes from all eaten to part eaten twice running each announce themselves without the sitter needing to judge whether they matter. Judgement stays with you; the log's job is faithful reporting in a fixed shape.
Agreeing What Earns a Phone Call
Before you leave, agree which field changes earn a call on the day rather than a line in the log. Sensible triggers are a fish that cannot be found, a temperature figure clearly outside the range you have written on the log page, a water level falling despite a top-up, or food refused at two visits in a row. Write those triggers on the log page itself, under the headings, so the sitter decides by the page rather than by worry.
Everything else waits in the log for your return. That split protects the sitter from carrying decisions that are not theirs, and protects you from a trip interrupted by reports that the log would have carried perfectly well. When you return, read down each column once, thank the sitter, and file the page with the tank's ongoing record so the trip becomes part of its history.
KinsLe puts the headed log page in the sitter's hands for each visit, and its Care Pass shares the six fields, the stock list, and your call triggers together until you are home.
