Chili Rasboras: Everything You Need To Know


The chili rasbora is a tiny, beautiful fish. These schooling fish are great fish to spice up almost any nano aquarium. Even if it’s only a 5 gallon tank.

In this care guide, I’ll show you almost everything you need to know to start keeping these beautiful, little fish!


red fish in tank

The chili rasbora is very small. Because of this they really don’t need a large tank at all.

They are red in color and a red and black stripe on the side of their body. Sometimes you may see a chili rasbora with a black dorsal fin as well.

Usual Behavior

Saying that these fish are schooling fish, they should be in a school of at least 6 individuals.

If they aren’t in a school, they could get stressed which just isn’t healthy for them, so be sure to get a school!

They aren’t known to be super aggressive. So, you don’t really have to worry about these fish picking on any of your other fish.


Although you wouldn’t think that these fish live that long, they actually do.

In fact, they can live for up to 8 years! That’s longer than a betta fish!


These fish are super tiny. In fact, they don’t even get an inch long!

Because they are so tiny, you can actually keep a large amount of them in a small tank.

Chili Rasbora Care

Make sure to care for these fish properly so they can live a long life.

Remember that for some fish, the healthier they are, the more colorful they are.

Tank Size

Because of their extremely small size, they can easily live in a 5 gallon aquarium.

You could keep a school of about 10 in a 5 gallon tank. Remember you can still overstock the tank, so make sure to get the right amount of fish for your tank.

Tank Mates

Some suitable tank mates for these fish include:

  • Neon tetras
  • Other rasboras
  • Dwarf gourami
  • Cherry shirmp


Saying that these fish are so tiny, finding food that can actually fit in their mouth can be a challenge.

These little guys are omnivorous which means they will eat meat and vegetables. But don’t feed them steak or anything though. 😉

You can feed your chili rasboras small bloodworms, fry food, baby brine shrimp as well as flake food. Just make sure that you crush the flakes into tiny pieces.

Water Parameters

You need to make sure that the water parameters are in the ideal range.

If the water parameters are off, it could cause your fish to stress which will make them susceptible to disease. Make sure to keep the water parameters in following range.

  • pH: 4.0-7.0
  • Temperature: 68-83°F
  • Water hardness: 1-10 dKH

Possible Diseases

Here are some of the diseases that chili rasboras can get.

  • Ich
  • Cotton Mouth Disease
  • Fungal infections

Typical Price

The online stores I visited sold them for 5-6 dollars an individual.

Remember that you could pay more or less per individual. It really depends on where you buy them.
