A decent home
A filtered, heated tank with a lid is the baseline. Room-temperature Australian winters are too cold for most bettas. Live or silk plants give rest spots without tearing fins.
Weekly care
- Heat in the mid-20s °C unless your vet or species notes say otherwise — use a heater and thermometer, not guesswork.
- Partial water changes with dechlorinated water matched to temperature.
- Feed small portions; skip a day if the belly looks round.
- Do not house two males together. Female groups need more skill and space.
Buying or rehoming
Ask how the fish is kept now. A betta from a tiny cup needs slow acclimation into a cycled tank. List honestly on MateLoop if you can no longer keep them.
