Chili Rasbora
The Chili Rasbora (Boraras brigittae) is a beautiful nano freshwater fish known for its intense red coloration, small size, and peaceful schooling behavior. Even though they stay tiny, Chili Rasboras can add a huge amount of color and movement to a properly set up aquarium.
These peaceful nano fish do best in mature, well-planted aquariums with gentle filtration and stable water conditions. When kept in groups and given plenty of plant cover, their red coloration can become especially bright, making them a stunning choice for nano tanks, shrimp tanks, and aquascapes.

Chili Rasboras should be kept in groups for best color, confidence, and natural behavior. A group of 8 is the minimum recommended, but 12 or more is even better when tank size allows.

Frequently Asked Questions
Are Chili Rasboras good for beginners?
Chili Rasboras can be good for beginners who have a stable, mature aquarium. Because they are very small, they do best in tanks with gentle filtration, stable water quality, and peaceful tank mates.
Can Chili Rasboras live with shrimp?
Yes. Chili Rasboras are commonly kept with shrimp and are a great choice for peaceful shrimp tanks. Very tiny baby shrimp may still be eaten, but adult shrimp are usually safe.
Do Chili Rasboras need live plants?
Live plants are strongly recommended. Plants provide cover, reduce stress, improve natural behavior, and help their red coloration stand out.
How many Chili Rasboras should I keep?
Keep at least 8 Chili Rasboras, but a group of 12 or more is even better. Larger groups help them feel more secure and show better natural schooling behavior.
Do Chili Rasboras jump?
They are not extreme jumpers, but a lid is still recommended. Small fish can jump when startled or stressed.
What do Chili Rasboras eat?
Chili Rasboras need very small foods such as micro pellets, finely crushed flakes, baby brine shrimp, daphnia, cyclops, and powdered foods.
What size tank do Chili Rasboras need?
A 5-gallon aquarium can work for a small group if it is mature and well-maintained, but larger planted nano tanks provide more stability and room for a better school.
