A medicine-free observation period only proves anything if the log shows two things side by side: the fish was watched closely every day, and nothing was added or done to the fish during that watching. For a new cichlid in quarantine, the log is the method. Short, same-shaped daily entries turn a vague feeling that the fish seems fine into a dated record another keeper, or a vet, can actually judge.
The Fixed Fields for Every Entry
Use these fields, in this order, for every single entry: date, appetite and food eaten, behaviour and tank position, breathing at rest, waste appearance, visible marks or changes. A worked entry reads: Date: 2025-06-02, evening check. Appetite and food eaten: took all offered food at the surface, searched the sand afterwards. Behaviour and tank position: holding the middle water near the rock pile, exploring rather than hiding. Breathing at rest: even and unhurried while resting by the rocks. Waste appearance: formed and dark, passed without trailing strands. Visible marks or changes: fins fully spread, no spots, patches, or fraying seen. A second entry the following day uses the identical fields, even if every line simply repeats that the fish looks the same, because sameness written down daily is the substance of an observation period.
How to Observe Without Intervening
Watch at the same time each day, ideally around feeding, when appetite and behaviour can be judged together. Stand back for the first minute and read the fish undisturbed: where it sits in the tank, how it holds its fins, and whether its breathing at rest looks even before it notices you. Then feed the normal ration and record what was eaten and what was left. Look along the body and fins in the tank light for any mark that was not there yesterday, and check the tank floor and filter outflow area for waste you can describe. Keep hands, nets, and additives out of the quarantine tank on observation days; cleaning that must be done should be plain siphoning and replacement water matched to the tank, and it stays out of the log entirely, because those fields describe the fish, not the maintenance.
What Counts as a Change Worth Acting On
Compare each entry with the entries before it, not with a general idea of cichlid behaviour. Act sooner rather than later when the log shows a direction of travel: appetite falling across two or three entries, food taken then spat out repeatedly, breathing at rest becoming rapid or laboured, the fish retreating to a corner or the surface and staying there, waste turning pale and stringy day after day, or a new mark spreading between one entry and the next. Any one of those changes, written in your own dated words, is the point to stop observing on your own and ring a vet or an aquatic specialist, describing the change and the day it first appeared in the log. Do not reach for a remedy to add to the water instead; the value of a medicine-free period is that the specialist hears an untainted history, with dates, rather than a story muddled by things already tried.
Closing the Period
End the log with a short summary entry once the cichlid has eaten, breathed, and behaved in the same settled pattern for the full run of days you set yourself: total days observed, the pattern of appetite across them, and the date the fish moved to its main tank. Keep the finished log rather than discarding it at the move, because the first weeks in the main tank will be read against it whenever behaviour shifts. Filed inside KinsLe, your Pet Passport holds that quarantine history on the cichlid's own page long after the quarantine tank has been emptied and put away.
