On the same day each month, write exactly three lines for your betta and take one photograph in the same light from the same position. Line one records where he rests. Line two records his appetite, described by how eagerly he comes to food and whether he finishes it. Line three records his colour and fin condition as they look today. Ageing in a betta is gradual, so the value of the note lies in the comparison. A single month tells you little. Six monthly entries in a row show a trend while it is still small.
Line One: Resting Spots
Write the exact place, not a general impression. Note whether he rests on a particular leaf, on the substrate, behind the filter, or near the surface, and how long he stays there at a stretch. An older betta often rests more and chooses softer, shallower support, so a move from open swimming to a favourite leaf is worth recording rather than worrying over on its own. What matters is change: a fish that suddenly rests on the bottom all day, after months of resting on leaves, has given you a dated observation to describe to a vet.
Line Two: Appetite in Plain Words
Record how he behaves at feeding, in words you will understand a year later. Write whether he rose quickly or slowly, whether he struck at the first piece or ignored it, and whether he finished his usual portion. Avoid scores or stars, because a number without the behaviour behind it cannot be compared next month. Keep the food and portion steady on note day, so the comparison reflects the fish and not a changed menu. If he refused food on note day, write that plainly and note whether he ate normally the next day, still inside that same second line.
Line Three: Colour, Fins and the Photograph
Describe colour by area: head, body, and fins, noting any fading, darkening or pale patches you can see today. Add fin condition to the same line, including whether the edges look smooth, split or ragged today. Then take the photograph that belongs with these three lines. Use the same lamp or window light, the same side of the tank, and the same distance each month, with the flash off. A photograph taken in different light can make a healthy fish look faded, so consistency is what makes the comparison fair. Write line three from what you see in front of you today, and save the comparison with last month's photograph until all three lines are written.
Keeping the Monthly Set Together
Keep each month's set complete and in order: the date, the three lines, and the one photograph. Do not add extra fields on some months and leave them out on others, because gaps make trends hard to read. If you keep two bettas, keep a separate monthly set for each fish and label it with the fish's name at the top of the page. Read down the last three or four sets at each sitting. Note-day discipline protects the record: always observe before feeding, write the three lines before you look back at older entries, then compare, so this month's wording reflects this month's fish rather than your memory of last month's page. A slow drift in resting place, appetite and colour together deserves a vet conversation, with the dated notes and photographs in hand. In KinsLe, Pet Passport storage keeps each monthly set filed under your betta's own profile, so the record you bring to an appointment is the full sequence rather than scattered phone pictures.
