The Sale Note, With Numbers and Sexing Explained
Start with a receipt or transfer note naming the seller or breeder and stating how many scarlet badis you are taking. Then add the detail this species always needs: how those fish were sexed. Females are scarce in the trade, plainer and rounder than the vivid red-banded males, and shops have historically sold mostly males, so a written note of what you were sold, and on what basis, protects you if a supposed pair turns out to be two rivals. Two males in a small tank will spar and suppress each other's colour, and your purchase record is what lets you return to the seller with facts rather than impressions.
Wild-Caught or Tank-Bred: the Origin Record
Ask where the fish came from and write the answer down. Scarlet badis originate from slow, plant-choked waters in northern India, and a large share of shop fish are wild-caught, arriving shy, sometimes thin, and conditioned to hunt moving prey. Tank-bred fish are usually bolder and more flexible about food. Knowing which you have changes what normal looks like during the first month: a wild-caught male hiding in the plants and refusing dry food is behaving predictably, not necessarily failing. Origin also matters if you pass the fish on, because the next keeper deserves the same honest starting point you needed.
Feeding History for a Fish That Hunts, Not Grazes
No section of a scarlet badis file matters more day to day than food. These are micropredators that inspect, stalk, and strike small live prey, and many individuals never accept flake or pellet at all. Get the seller to record exactly what the fish have been eating, whether frozen foods were taken, and how often they were fed. Then log your own offerings and responses during the first weeks, noting which foods trigger a hunt and which are ignored. If the fish later loses condition, that side-by-side record separates a feeding problem from illness far faster than memory, and it is the first evidence an experienced shop will want when advising you.
Health History and a Careful Arrival Log
Ask whether the selling group has shown sunken bellies, clamped fins, or recent deaths, and record the answer with the sale note. On arrival, describe each fish's colour and belly shape, which territory it claimed among the plants and caves, and how it interacted with tank mates, because badis stress often shows as withdrawal and fading rather than obvious symptoms. Update the log when a fish starts courting, spawns in a cave, or drives a rival away, since each event changes the social picture in the tank. Small written observations, made early, become the baseline that makes later trouble recognisable.
Passing the File on With the Fish
Scarlet badis are frequently rehomed when a nano tank is rearranged or males outgrow their truce, and a fish that travels with its sexing note, origin, and proven menu settles far better than one that arrives as a mystery. Keep those records with your own log, and revise the feeding section whenever the fish accepts something new. Good paperwork is a genuine welfare tool for a species this particular about food and company. Filing the seller's notes and your territory and feeding log in the Pet Passport in KinsLe means your scarlet badis carries its essential history into any future tank or home.
