The Chili Rasbora is a beautiful freshwater fish that makes for an excellent pet. 

You don’t need to have a lot of experience with keeping fish to take care of this one. In this article we will cover everything you’ll need to know about caring for these fish properly.

Chili Rasbora Appearance

These fish have a slender reddish orange body with a black streak that runs down the side of their body. Males are usually more brightly colored than the females, but all of these fish are quite striking. The males also have splotches of bright red all over their fins, which makes it look like they are floating in the water.

The middle of these fish are where they are thickest, but they get increasingly slender back towards their wide tail. These fish can get up to almost an inch long. The females are actually usually a little larger than the males.


The main reason that Chili Rasbora fish are so easy to care for is because of their docile nature. They are known for being very peaceful and get along with most other fish very well. You can expect your fish to spend a majority of its time swimming around the top part of the tank. While these fish sometimes go a little further towards the bottom, this doesn’t happen very often.

If you decide to keep more than one of these fish in the same tank, they will almost certainly form into a school. These fish travel together in the wild out of instinct, as it helps keep them safe from predators.

1. Tank Setup

You will need a tank that is at least 5 gallons if you are going to keep a Chili Rasbora. The tank should be at least double this size if you plan to keep more than one. Bigger is always better, especially with fish like these that tend to be very active. You’ll want to give them adequate space to swim around freely.

You should put at least two or three small to medium size plants in your fish tank. While they do love to swim around, they will always need a place to hide out sometimes. This is especially important if you are planning on keeping just one of these fish. They are going to feel a lot more vulnerable if they don’t have any of their own kind around.

2. Water Conditions

It is best to keep Chili Rasbora fish in water with a pH level of 5 or lower. Make sure that you use a testing kit to monitor the acidity level of the water. Keep the temperature of the water within a range of 74 to 82 degrees Fahrenehit. There shouldn’t be any ammonia or nitrate present in the water.

You will absolutely need to use a heater to keep your fish comfortable in their new environment. These fish are used to tropical waters, so a good heater is a must. Avoid keeping the tank in any spot that receives direct sunlight, as this can cause the water to become too hot. If the tank is close to a window, it should be curtained.

3. Chili Rasbora Tank Mates

While Chili Rasboras are very peaceful, you don’t want to keep them with just any fish. There are certain types of fish that make for better tank mates than others. Some of the best fish to keep with this one include Dwarf Shrimp, Neon Tetras, Sparkling Gouramis, and Celestial Pearl Danios. You’ll want to focus on fish that are around the same size so that none of them end up getting bullied or abused.

4. Chili Rasbora Food

You will be able to give these fish small pellets or fish flakes on a daily basis without any issues. They should, however, also be given a good amount of protein. There are plenty of live or frozen foods that can satisfy this nutritional requirement, including micro worms and brine shrimp.

Common Health Problems

Fortunately, there aren’t a lot of serious health issues that Chili Rasboras are prone to. Bacterial infections can be a serious concern, so you’ll need to keep their tank as clean as possible. Make sure that you change out all of the water in the tank every week or so, and replace 30% of the water every few days.

Chili Rasbora Breeding

It is actually incredibly easy to breed these fish, so you shouldn’t experience any major issues with doing so. You should have another tank that is dedicated to this purpose. Make sure that you remove the parents from the tank as soon as the fry are born so they won’t be in any danger of getting eaten.
