Barbels and breathing lead the corydoras record
Barbels lead a corydoras vet note because those whiskers show wear from the substrate before anything else on the fish changes. Record the vet's description of barbel length and condition on each side, then findings on belly fullness, fin condition, skin, and breathing rate, including how often the fish was darting to the surface before the visit. Write the presenting concern first, in order of when signs appeared: shortened whiskers, sitting still on the bottom, flashing against objects, or refusing food that sank nearby. Separating the vet's examination findings from your home account matters, because a cory lifted into bright light breathes fast whether it is ill or simply frightened.
Substrate and group details the vet will act on
Substrate and group answers belong in a corydoras record because bottom life is this species' whole environment. Note what the vet asked and what you replied about gravel versus sand, how the substrate is cleaned, how many corydoras share the tank, and whether all of them are the same species. Record any instruction to change substrate, deepen the group, or adjust bottom feeding in the vet's exact wording. If the vet linked barbel wear to sharp gravel or to food never reaching the bottom past faster fish, that reasoning should sit beside the instruction, because it is the part you will need when deciding whether a future tank needs the same fix.
Instructions and the bottom-specific call-back signs
Instructions in a corydoras note should include the call-back signs in bottom terms. Copy the home care plan, any water change schedule the vet set, and the signs named for getting back in touch: barbels shortening further, a fish resting tilted, redness around the mouth, or the whole group going quiet on the substrate. If the vet wants a photo check before a full return visit, note which view is needed, since a clear mouth-and-barbel shot of a corydoras takes patience and a sinking wafer to arrange. Do not compress the plan into your own shorthand until the original version is written out in full.
Recovery looks like sifting, schooling, and surface trips
Home follow-up for a corydoras is written in bottom behaviour. Log when the fish resumed sifting substrate with its barbels, whether it rejoined the group's resting cluster, and how often surface trips happened compared with before the visit. Note whether sinking food was found and eaten or left, and which tankmates reached it first. Add a barbel line every few days using the same description words as the vet's note, so progress is comparable rather than impressionistic. A corydoras that is sifting, schooling loosely, and making only occasional calm trips to the surface is telling a recovery story your log can prove at review.
File corydoras notes with a barbel photo series
Corydoras visit notes should be filed in order with the clearest barbel photo from each episode attached, building a series that shows whisker condition across the fish's life better than any single description. Index each visit by concern and headline finding, and keep substrate or group changes recorded against the visit that prompted them. Retain the full set while the group is kept, since tankmates usually share the same bottom conditions and one fish's episode becomes the reference for the next. Kept in that order, KinsLe can hold the visit notes and barbel series together in the Pet Passport for your corydoras catfish.
