The Redstripe rasbora is a slender rasbora from the peat swamp streams of Southeast Asia. An orange-to-gold stripe runs along each side, with a darker line beneath it, giving the fish a neat, streamlined look. Kept in a group, the stripes move together and bring life to the whole tank. Adults reach up to 7 cm in total length and have a peaceful temperament, so they pair well with other calm, small fish. They prefer soft, slightly acidic water, yet are considered beginner-friendly and do well in a quiet tank set up with plants and driftwood.

About Redstripe rasbora
A slender, peaceful rasbora from Southeast Asian peat swamps with a glowing orange-gold side stripe. Growing to 7 cm and suited to beginners, here are the care tips to read before you bring one home.
7 things to know before welcoming a Redstripe rasbora
1Best kept in a group
Redstripe rasboras are schooling fish, and a lone individual may seem uneasy and hide more often. Keeping several together shows off their stripes moving in unison. A tank with generous horizontal swimming space suits a group well.
2Soft, slightly acidic water
They come from peat swamp streams and prefer soft, slightly acidic water. Sudden changes in water quality can stress fish, so change water in small amounts and check conditions regularly.
3Feed small-sized foods
This is a slim, small fish with a small mouth, so fine-grained prepared foods and small frozen foods are easiest for it to eat. Uneaten food can foul the water, so feed small portions and remove leftovers promptly.
4Choose calm tank mates
Their temperament is peaceful, and they generally get along with other quiet, small fish. Avoid housing them with large or aggressive species, which may chase or eat them. Compatibility can vary between individuals, so watch the tank and adjust as needed.
5Use a tight-fitting lid
Rasboras can leap from the water when startled. Cover the tank with a lid that leaves few gaps, and close off any openings for tubing or cables.
6Give them shade and cover
Since they live in peat swamp streams, plants and driftwood that create shade and hiding places help them feel settled. A dark substrate can make the orange-to-gold side stripe stand out more clearly.
7Acclimate carefully on arrival
When your fish arrives, float the bag in the tank to match temperature, then add tank water little by little to adjust it to your water. Fish can be tired after transport, so keep things quiet for a while and feed lightly at first.

- A.The species guide lists its care difficulty as beginner-friendly. Since it prefers soft, slightly acidic water, avoid sudden water changes and keep it in a group.
