Rasbora Fish

Rasbora fish are one of the easiest ways to fill out a peaceful community tank with movement and color without adding aggression or bioload. Native to the slow-moving blackwater streams of Southeast Asia, Rasboras range from true nano fish barely a fingertip long to larger, silvery schoolers built for bigger community tanks. Below you'll find every rasbora species we currently stock, sorted so you can shop by size and tank fit first, then dig into full care details on our dedicated guides.

How to Choose the Right Rasbora for Your Tank

• Match the fish to your tank size first. A 5–10 gallon nano tank is a great fit for true nano rasboras like Chili or Strawberry Rasbora; save Harlequin, Lambchop, Scissortail, or Brilliant Rasbora for a 10-gallon-or-larger community setup where they have more room to school.
• Buy the full school at once, not one or two at a time. Rasboras are shoaling fish — an under-sized group is more stressed, shows duller color, and hides more. Add the whole recommended school size in one trip whenever your tank and filtration can support it.
• Think about existing tankmates. Nano rasboras pair naturally with shrimp and snails and other peaceful nano fish; mid-size and larger rasboras do well in general community tanks alongside Corydoras, Gouramis, and calmer Betta fish — see our Harlequin guide above for the specific compatibility notes.
• Plan for a planted tank if you can. Nearly every rasbora we carry does best with soft lighting and cover from live plants, which mirrors their native blackwater streams and shows off their color.

Rasbora Fish Shopping FAQs

What's the difference between Harlequin, Chili, and the other rasboras you carry?

The biggest difference is size and tank fit. Harlequin Rasbora and its close relatives (Purple Harlequin, Lambchop) run about 1.5–2 inches and suit a 10–20 gallon community tank, while nano species like Chili, Strawberry, Dwarf, and Phoenix Rasbora stay under an inch and are built for 5–10 gallon nano setups. Scissortail and Brilliant Rasbora are the largest fish on this page and need at least 20 gallons. Use the table above to compare, and see our Harlequin Rasbora Care Guide for the deepest species-specific detail.

Which rasbora is best for a small nano tank?

For a 5–10 gallon nano tank, choose from our true nano species — Chili Rasbora, Strawberry Rasbora, Dwarf Rasbora, Phoenix Rasbora, Neon Blue Rasbora, Exclamation Point Rasbora, Kubotai Rasbora, or Rummynose Rasbora — all of which are comfortable in a school of 8–10+ within that footprint.

Can I keep two different rasbora species together in one school?

Rasboras school most naturally with their own species, so we recommend a full group of one species per tank rather than splitting the count across two. It's fine to stock two different rasbora species in the same aquarium as separate schools, as long as the tank is large enough to support both group sizes and their size difference isn't extreme (for example, pairing several nano species together is easier than mixing a nano species with a larger-bodied one).

Do all rasbora species need the same tank setup?

The broad strokes are similar — soft lighting, live plants, gentle filtration, and a peaceful community — but exact tank size and school size shift with adult size (see the table above). For full setup steps, water parameters, and diet for our most-searched species, use the Harlequin Rasbora Care Guide rather than guessing from a single generic care sheet.
