 Chili Rasbora Overview

The Chili Rasbora (scientific name Boras London) is a nano fish that plays swimming and playing in school. They are not only attractive fish, they have great personalities. They have all the benefits in one small package.

A native of southwestern Borneo, Indonesia, the Chili Rasbora, also known as the Mosquito Rasbora, is one of the smallest tropical fish in the home aquarium. Men are known for their bright ruby ​​red color (when properly cared for).

Originally described by Dieter Vogue in 19ter3, the name of the Chili rasbora was Rasbora Brigita in honour of Dieter’s wife, Brigitte. The Chili Rasbora is not a true Rasbora and was placed in the Boraras dynasty in 1993.

The nickname of the modified ego Mosquito Rasbora comes from the natural habitat of the Rasbora in Chile which glows with the mosquito.

At a time when there are several Boraras species in the aquarium trade, Chili raspberries are a hobby choice because they are so beautiful to look at.

Chili Rasbora Typical Behavior

Occupying the top and middle of the water column of the aquarium, the Chili Rasbora is easy to find despite its small size. And although they like top and medium, don’t be surprised if you see them swimming and eating at medium and low levels.

The Complete Guide to Chili Rasbora Care

When they come together as a school, they are not predictable but never bother to visit. They get very cool with fish and other peaceful fish and invertebrates.

Make sure you have a tight-fitting cover in your aquarium. Although Chili raspberries are not known for jumping, they sometimes try to jump out of the tank and these are so small that you run the risk of losing them.

 Chili Rasbora Appearance

Stunning creatures, the Chili raspberries have a dark stripe next to their red bodies. This dark band contrasts with a dark red band above the dark band.

They have small dark spots at the base of the anus and the wings of affection.

Male Chili raspberries can be distinguished from females by their dorsal and anal fins, which have bright red stripes.

At one inch (18 mm), these beauties are actually nano fish.

Chili Rasbora Habitat and Tank Conditions

To get the best color, be sure to equip your Chili raspberries with floating trees and an aquarium planted with a dark layer. Ideal for finely textured sand or gravel nano chile raspberries.

These conditions will promote better health of these small fish.

In their natural environment in Borneo, they settle in blackwater streams and pools, so a dark layer for a dark background will fill their gaps.

Their natural habitat includes low water with low pH, so they will need it in your home aquarium.


They will enjoy a colorful environment that includes both trees and floating plants. The roots and branches mimic their environment and the hanging plants confine direct light to the Chili rasbora.

While you can put them in five-gallon nano-tanks as six small schools, if you put them in a big tank you will have enough space for a huge and beautiful school, which will make a school running light show in your aquarium. .

If you include live plants in your aquarium, not only will there be a cover to explore them, but floating plants will make a home for plankton and worms, these are the right size snacks for a little mouthful of Chili Rasbora.

The plant cover, as we mentioned, will let the light in the tank dampen, which encourages the development of more intense and bright colours.

The state of the water

The natural environment of the Chili Rasbora has a slow water flow, so you need to create the same water situation in your home tank. These fish are extremely small and they will not be able to withstand a strong current.

To deal with any current that is too strong, add currents, driftwood, logs and other decorations to break the current. In addition, the plants will also help in the flow.

They need a filter because they need pure water to survive; Just make sure the filter is not too strong. Since these are so small any change in water conditions can be fatal, so you need to monitor and maintain stable settings.

In addition to a slow flow, pepper raspberries prefer water that is both soft and acidic. You will need a test kit to monitor the levels and you can use dilute the water to create the right situation or use reverse osmosis to dilute the tap water.

If you need to lower the pH level, there are natural remedies that can be used instead of additives. These include peat (algae) and almond leaves – these natural additives release tannins that lower the pH.

Pro Tip: The presence of tannins and the low pH they provide is good for the health of the Chili Rasbora, reducing germs in the water and preventing illness.

The optimal parameters to ensure a close match with their natural habitat are:

  • GH: 1-2
  • KH: 3-12 dKH
  • pH: 4.0-7.0
  • Temperature: 68-82.4° F (20°-28° C)

While Rasbora Peppers have this wide acceptable temperature setting, they need the stability we talked about, so be sure to maintain a constant temperature.

For this reason, don’t be fooled by the low-temperature range and think you don’t need any heaters. Changes in ambient temperature can change the water temperature in the tank and create pressure for cold-water fish. Stressful fish have compromised with health, lifespan, colour and mood.

Set the heater at one stage within the acceptable range of 68-82.4 F (20 -28 ° C) and hold it for a happy, healthy, stress-free Rasbora pepper.

In addition to maintaining a temperature that is not too cold, you also want to make sure that the temperature is not too hot – Chili raspberries can easily overheat over long periods of direct sunlight (another reason why plant covers are beneficial for these nano fish).

Water conditioner

The tap water supply contains chlorine and other additives to keep it clean but these additives are toxic to fish, so you should use soft water designed for your aquarium.

What size aquarium does Chili Rasbora need?


A 5-gallon nano-tank will have a small school of 6 Chili rasbora. If you want bigger schools or they are joining a community aquarium, you will need a bigger tank. Keep in mind that these nano fish prefer dense habitats but they also need a swimming room.

How Many Can Be Kept Per Gallon?

You want to make sure that Rasbora Chile has at least one of the six schools. Less than that and they won’t be happy – they’ll be together to mean you can put two Chili raspberries in each gallon, so six fish would be acceptable for a 6-gallon tank.

Chili Rasbora Tank mate

Chile raspberries are a great cold fish and you will find it with other cool and small fish. It works well with small ornaments like dwarf shrimp. Stay away from aggressive and larger fish that both steal their food and turn it into food.

Suitable tank mate for Chili Rasbora:

  • Amano Shrimp
  • Celestial Pearl Danios
  • Cherry Shrimp
  • Chocolate Gourami
  • Cory Cats
  • Neons
  • Sparkling Gourami
  • Wood Shrimp

Putting the Chili raspberries together

In the case of fish schools, Chili raspberries must stay together. The minimum number of a school is six Chili raspberries. However, they will be happier (and more fun to watch) if they are in a large school of 20 or more fish.

Chili Rasbora Diet

Although these are omnivorous, Rasbora peppers prefer a muscle diet. Fresh or frozen, like cut bloodworms and micro worms, provide them with a variety of flux, granules and frozen dry protein sources.


To ensure the best color and health of your Rasbora pepper, be sure to give it a variety of nutritional sources. Be careful not to eat too much of these fish – they are too small and can get sick if they eat too much, and the more they eat, the more waste they create, which can make the water dirty and sick.

One more thing to keep in mind is that because of the nanoscale they all need cut and pulverized food. For example, flakes must turn into a powder.

Chili Rasbora Care

It is very important to keep the Rasbora Chile tank shamelessly clean. You need to clean the substrate and change the partial water regularly.

These are tough fish, but they are very small and they are very sensitive to changes in water conditions and cannot tolerate dirty tanks.

If their reservoirs are not properly maintained, they are at risk of disease and illness. Conditions that can affect your pepper Rasbora include fungal infections, bacterial infections, and parasites at will. You need to isolate your sick fish and treat them with Ich drugs or over-the-counter drugs available at fly shops and aquariums.

You can also find physical manifestations of stress on their tiny bodies, low water quality or bad parameters or damaged food)

Common symptoms that may indicate that you are ill include:

  • Bloating
  • Bloody streaks (Ich)
  • Discolored Scales
  • Fuzzy cotton-like growths
  • Grey spots
  • Lesions
  • Pimples (Ich)
  • Pop eye
  • Red streaks
  • Red ulcers
  • Scratching (Ich)

Chili Rasbora Breeding

When ready for breeding, the male Chili raspberries turn a bright red, so you can call them female except. In addition, the black and red markings on their dorsal and tender wings are even darker.

On the other hand, females will look round and round because they carry eggs.

Pro Tip: Be careful since the males of the Chili Rossbora can get some territorial during breeding and they can fight, so you need to make sure you have enough space of your own so that each of them has their own small area.

You will see the male Nanos showing the female to attract if she achieves it, the female will lay a small number of eggs which she spreads at the bottom of the tank.

And this is the end of parenting. Neither male nor female Chili raspberries actively care for their eggs. In fact, they are known to brutalize their own eggs.

If your home aquarium is dense enough, their fish tank for midnight snacks may have enough cover to survive fried despite the threat of other fish (unless their own parents are mentioned!) To do this, you need to set up a separate breeding tank.

They reproduce fairly seamlessly, so there is a chance to give your fries a chance to fight in a separate breeding tank. You can feed Infusoria and Paramesia fry until they can handle large meals.

You need 1 to 2 females for each male in your tank and you need influential males to create the best balance of reproduction.

The configuration of the breeding tank should be as follows: Add small groups to the egg spreading container, the nets at the bottom are small enough to hatch but small enough that the parents cannot access and eat the eggs.


It’s fun to see their spawn – they look like they’re chasing each other in a tank. Male and female Chili raspberries can be kept in the breeding tank for three or four days, but they must be returned to the original tank.

If you leave it in the breeding tank for longer than that, the fried Chili raspberries are in danger.

Keep in mind that Chili raspberries are particularly sensitive to water changes, so if you are using a breeding tank, you need to make sure your temperature, solubility, pH, and hardness are compatible with both tanks; Otherwise, you may lose the fish during the transfer because they cannot tolerate turbulence.

Chili Rasbora Common health problems

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

Are Chili Rasbora Suitable for your Aquarium?

Lots of Chili raspberries in a small package. They are gentle and shy; They are beautiful to look at with their bright colors and playful antiques and they blend well with other cool little fish.

  • The active and playful nature of these fish is why they are so popular. They spend a lot of time at the top of the tank.
  • You should keep your raspberries in at least a 5-gallon tank, although 10 gallons is ideal. These fish need enough space to swim.
  • Always keep the water temperature between 75 and 82 degrees. A good heater is necessary since these fish are used to warm tropical waters.
  • Make sure that the tank is not exposed to direct sunlight.
  • Dwarf shrimp and neon grouse are both great tank mates.
  • You can give these fish regular flakes or small chunks of small chickpeas, but the protein in the form of brine shrimp and microsomes is also important

Is Rasbora chile your favourite tropical fish? Why in the comments below …


Q: Why do Chili Rasbora need so many plants in the tank? 

Answer: There are various reasons to appreciate the fact that Chili raspberries appreciate both greenery and floating plants. It mimics their natural habitat in Indonesia, hiding places and providing nutrition to microscopic animals gathered in the leaves of trees.

Lash trees filter light so that Chili raspberries are not exposed to excessive heat and light (in fact, the best color vitality comes with less light).

In addition, they swim through a lot of aquatic plants while swimming with their schoolmates. They like to explore under the green ceiling.

Q: Should I keep more than one Chili Rasbora in my home aquarium?

  1. Absolutely! Chile raspberries are a schooling fish and we do not recommend having less than six in the aquarium. These are designed to stay together, so if you’re getting one or two (or less than six, really) your mind isn’t stressed.

Being with their own species gives them stability and protection and also gives them the opportunity to swim together which is very important for these active small nano fish. If you put less than six Chili raspberries together, you will definitely notice a change in their mood and mood, but you will also see that their colors are less transparent and they get sick more easily.

In fact, we recommend that you get a tank larger than five gallons so that you can keep at least 20 schooling mate and more than that.
