Chili Rasbora Tank Mates

Chili rasboras (Boraras brigittae) are small fish that will be great tank mates for many other peaceful fish of similar size.

Since Chili rasboras are peaceful fish, you do not need to worry about them attacking other fish. However, it is important to make sure they do not get attacked by other fish when choosing tank mates for them.

When choosing tank mates, tank setup and water parameters is another important consideration. Even if the fish are able to get along peacefully, if the fish can not co-exist in the same environment due to different requirements it would not work. Learn about their requirements from our Chili Rasbora Care Guide.

When considering tank mates, make sure there is enough space for all fish. Chili rasbora are schooling fish, so make sure there’s enough of their own species before considering tank mates of different species. There should be a minimum of 6 Chili rasboras in the tank at all times. They will feel more comfortable as a group.

Make sure that there is enough hiding places for the fish as well. A combination of hardscape and live plants would provide the hiding places that they need, and mimic their natural environment as well. Even if compatible tank mates are selected, it can get stressful when new fish are introduced. Having areas that will allow them to hide and destress will contribute to the success of a community tank.

While there are many aquarium fish species, keep in mind that there are compatible and incompatible tank mates for Chili rasboras.

Now let’s dive into more details on specific tank mates and how you can expect them to interact with Chili rasboras.

Betta Fish

Betta Fish (Betta splendens)

It is possible to house Chili rasbora with Betta fish under the right conditions. Both species of fish enjoy roughly the same water parameters and diet. Typically, territorial Bettas are kept in aquariums all to themselves as they do not do well with fish that invade their space, but if you are planning on keeping your Chili rasbora with Bettas, you will want to provide them with many places to hide and get away from one another. Both species come from natural environments that are full of leaf litter and debris, so setting up the community tank with this in mind will be most helpful in keeping these two species together safely.


Guppy Fish, Poecilia Reticulata

Chili rasbora and Guppies can coexist peacefully, and you will not encounter any issues between these two species as long as you are not overcrowding them. Both species require similar water parameters and diets to keep them comfortable, so if you have enough room, Guppies make great tank mates for Chili Rasboras.

Neon Tetra

Chili rasbora and Neon tetras are safe to be housed together in a community tank. Both species enjoy similar water parameters, and diets too. It is important to note that Neon Tetras are slightly larger than Chili Rasboras. This will not become an issue until feeding time. The larger Neon Tetras can easily outcompete your Chili Rasboras for food. This can lead to stress issues in your fish, and eventual decline. You will want to make sure to observe your fish together during feeding time to make sure that all of your fish are getting fed.

Cardinal Tetra

Chili Rasboras and Cardinal Tetras make another great duo in community fish keeping. Both are schooling species that enjoy spending their time swiftly swimming about in their aquarium. Both species enjoy similar water parameters and food requirements, so as long as you have enough room in your aquarium for both species to have a small school, they should do just fine together.

Other Tetras

Black Neon Tetra (Hyphessobrycon Herbertaxelrodi)

Chili Rasboras are safe to keep in a community tank setup with most small species of tetras, such as Black Neon tetra. The most important thing to keep in mind when considering Tetra tank mates for you Chili Rasboras is during feedings. You should always take the time to observe your fish together to make sure that they are all getting their fill during meals as the slightly larger Tetra species can out-compete your Chili Rasboras for food.

Cherry Shrimp

Red cherry shrimp

Housing Chili Rasboras with Cherry Shrimp can be done, but it is much more difficult to get the water parameters correct for both species than it is with anything else. Chili Rasboras are accepting of a wider range of water parameters as long as they are adjusted to it slowly. Cherry Shrimp requires a slightly cooler water temperature than Chili Rasboras. Owners of Chili Rasboras and Cherry Shrimp note that their Chili Rasboras do not bother their Cherry Shrimp other than occasionally eating a Cherry Shrimp fry. If you can manage to get their water parameters correct, you can definitely house these two species together without difficulty.

Amano Shrimp

Amano Shrimp (Caridina multidentata)

Chili Rasboras do well with Amano Shrimp in community aquarium setups. Since Chili Rasboras are hardy and can adapt to a wider range of water parameters, you can adjust your water so that it comfortably houses both of these two species. Just make sure that you do it gradually and not all at once as it could shock your fish and stress them out. Even though Amano Shrimp are small, you will find that your Chili Rasboras do not bother them. They will occasionally go after an Amano Shrimp fry, but typically they will leave them alone. Of course, it is a good idea to make sure your fish are well fed to help deter this.

Other Shrimp

Bamboo Shrimp

In general, Chili Rasboras are considered by many in the fishkeeping hobby a great species to keep with all species of Shrimp. Like with all new fish you add to your aquarium, it is important to make sure that you are observing them for a while to make sure that there are not any imbalances in your aquarium between the two species.


Dwarf Gourami (Colisa lalia)

Chili Rasboras can be safely housed with most species of Gourami. Gouramis are typically peaceful fish, but they are much larger than the small Chili Rasbora. If you are wanting to house these two species together in a community tank, it can be done as long as there are plenty of places for your Chili Rasboras to hide and get away. Both species enjoy roughly the same water parameters and diet.


Platy Fish

Both Platys and Chili Rasboras are considered peaceful species of fish, but it is probably not a good idea to pair these two in a community tank setup unless certain conditions are met. Platys are slow moving and can become easily stressed out by the rapid moving Chili Rasbora. Despite this, it is still possible to house these two species, but they need a lot more room than the standard requirement so that they can destress from one another.


Zebra Danio (Danio Rerio)

Chili Rasboras and Danios both enjoy roughly the same water parameters, and it seems at first as though they would make a great fit to house together in a community aquarium setup. After all, both species are considered peaceful with other species. However, it is not a good idea to house these two species together as Danios are much more active and fast than Chili Rasboras. It is said that fast moving Danios will stress out your Chili Rasboras.

African Dwarf Frogs

African Dwarf Frogs are small enough that they will not be an issue to keep in a community tank setup with Chili Rasboras. It is the larger species of Frogs that will go after your fish for food. African Dwarf Frogs and Chili Rasboras both enjoy similar water parameters and diet.

Other Tank Mates to Consider

Mystery Snail (Pomacea bridgesii)

Other tank mates to consider placing in a community setup with your Chili Rasboras are Loaches, Corydoras, and Snails. These species are peaceful enough, and require similar water parameters. 

List of Incompatible Tank Mates for Chili Rasboras

Since Chili Rasboras are small fish, keeping them with certain larger and/or aggressive species must be avoided.

Here’s a list of incompatible tank mates for Chili Rasboras:

  • Angelfish
  • Tiger Barbs
  • Oscar fish


Freshwater Angelfish (Pterophyllum Scalare)

It is not advised that you keep Chili Rasboras and Angelfish together in a community setup as Angelfish are not only aggressive, but they are territorial too. Chili Rasboras are much smaller than Angelfish are, and they will most likely end up as a meal for an Angelfish. Chili Rasboras are considered a nano fish, and as a general rule, it is not a good idea to house them with fish that are larger than 3 inches as it will cause stress to your smaller fish.

Tiger Barbs

Tiger Barb (Puntigrus tetrazona)

Even though Barbs are not a problematic species themselves, it is the tiny size of the Chili Rasbora that makes it difficult to house with other species. Chili Rasboras should not be housed with Barbs as they are just too small. Even though Barbs do well with other species of fish, they can not help themselves but to go after Chili Rasboras.
