How Many Chili Rasbora Should You Buy?
Chili Rasbora is a schooling species — it needs company to feel secure and show its best color and behavior. We recommend buying at least 6, and more if your tank has the room, since larger groups school more confidently and display more natural, active behavior than the bare minimum. This listing is sold per fish, so simply set the quantity to the school size you want (6, 8, 10, or more) before checking out — ordering your full school in one order also saves you a second shipping charge.
Tank Setup & Care Summary
Tank size: A 5-gallon tank can house a minimum school of 6 Chili Rasbora on its own; size up if you plan to add tankmates or a fuller school.
Water parameters: 75–82°F (23–27°C), pH 4.0–7.0 (slightly acidic is preferred), KH 3–12 dKH, GH 1–2 dGH.
Habitat: Native to slow-moving, tannin-stained streams and ponds in Borneo, Indonesia. Plenty of live aquatic plants and subdued lighting help them settle in and color up.
Diet: Despite being technically omnivorous, Chili Rasbora leans carnivorous — offer high-quality flake or micro-pellet food plus live, frozen, or freeze-dried Artemia, microworms, tubifex, or finely chopped bloodworms. Break food into small pieces so it fits their tiny mouths.
Temperament: Peaceful and active once schooled, but easily startled or outcompeted by larger, faster, or boisterous tankmates — choose calm, similarly-sized tankmates or keep them in a single-species nano tank.
Lid: Chili Rasbora isn’t known as a frequent jumper, but a tight-fitting lid is cheap insurance against the occasional startled leap.
