The Chili rasbora (Boraras Brigitte) is in some cases also called the Mosquito rasbora. These brilliantly colored, tiny fish only grow to measure around half an inch in size, making them one of the tiniest exotic aquarium fish you can purchase.
Chili rasboras are energetic yet relaxed little personalities, prospering in a neighborhood storage tank of other tiny, non-aggressive storage tank companions or a single-species arrangement when kept in a large college. These lovely nano fishes are relatively simple to care for, but they can be really sensitive to water’s high quality, so they’re not an excellent option for a novice.
In this thorough overview, we inform you everything you require to find out about caring for the shining swimming gem called the Chili rasbora.
Chili Rasbora summary
Chili Rasboras have actually been around for a few decades. But only just recently, with the surging appeal of nano fish, have they come to be much more typical in family pet stores.
They also go by the name “Insect Rasbora,” apparently because their finder, Dieter Vogt, was repulsed by the variety of insects discovered in their native habitat. Chili Rasboras are discovered in densely forested, tea-colored blackwater pools and streams; the perfect breeding place for mosquitoes.
Chili Rasboras are not just a few of the tiniest fish in the pastime; as adults, they are a few of the tiniest animals on the planet! 3/4 of an inch is a large grownup, with the average being somewhere in between this and 1/2 inch.
There are actually a few very closely associated species that are all part of the genus Boraras. Which makes complex things somewhat since the names are typically utilized interchangeably. Chili Rasboras are Boraras Brigitte, named after the better half of Dieter Vogt.
However, you might also encounter B. Merah, the Phoenix az Rasbora, B. naevus, the Strawberry Rasbora, and more. Most severe of all, none of the names I simply offered are used constantly by breeders other than Chili Rasbora … That stated, they all share similar care demands.
The other Boraras varieties have different spot patterns and some also have red stripes. Since many are still very new to the pastime I do not suggest maintaining them together. Closely associated fish like these are most likely able to crossbreed. This would certainly “pollute” the gene swimming pool ought to you market them back to a pet dog store.
While very small, all Boraras Rasboras are fantastic tropical fish for the right tank. But from here on out, we will certainly focus our interest specifically on the Chili Rasbora!
Authentic Habit Chili Rasbora
The Chili rasbora comes from Southwestern Borneo and also the Indonesian provinces of Kalimantan Tengah, and also Kalimantan Selatan.
The fishes’ natural environment includes blackwater pools and streams, where the circulation is really sluggish, and the peat-stained waters are very low in minerals and salts. The water pH here can be as low as 4.0.
The water is dark as well as dark, as well as the fish likewise enjoy plenty of concealing locations and cover that’s given by dropped leaves, immersed branches as well as origins, and also water plant life. The habitat is very protected and is shaded by overhanging trees and coastline plants.
At the time of composing, the Chili rasbora is not detailed on the IUCN Red Checklist. However, a lot of the fishes’ natural environment is quickly declining, so the types’ future in nature is by no means guaranteed.
Occupying the top as well as the center of the fish tank water column, Chili Rasbora is very easy to identify regardless of its small dimension. And although they prefer the leading as well as middle, don’t be surprised if you see them swimming and also eating at the center as well as lower levels.
When they get together as a college, they are unforeseeable, yet never ever tiring to watch. They are really peaceful fish and quadrate various other serene fish as well as invertebrates.
You ought to ensure you have a tight-fitting lid on your fish tank. Although Chili Rasboras are not known for jumping, they do often try to jump out of the storage tank, as well as they’re so tiny, you risk shedding them.
Their entire bodies are covered in tones of red and pink. The red coloration is most lively on a horizontal red stripe that runs the length of the body. Generally, men have a tendency to have an extra dynamic color of red than women.
Aquarium Size for Chilli Rasbora
As real nano fish, you have a lot of options when looking after Chili Rasboras. They are so little a group of six will certainly locate a 5-gallon aquarium rather comfortable. That said, they are really timid fish as well as prefer as a number of their own kind around as you can afford.
10+ adults are a lot more comfortable for both the Rasboras and you as you’ll get to observe their facility social dynamics. Inspired by the higher complacency your Chilis will be less reluctant and also more probable to stay out in the open.
If your filter is on the solid side you may intend to select a bigger aquarium to help distribute the flow rather. Most of the moment we want a filter with a high gallon per hour (GPH) score to process more water.
However, Chili Rasboras little fish from sluggish moving streams and also don’t appreciate having to combat versus a solid current. A larger storage tank enables you to guide the circulation someplace where the fish can run away from the assault.
Provided just how small their bioload is, even a sponge filter in a planted fish tank is more than enough for a species tank with simply Chili Rasboras.
Best Water Conditioner for chili Rasbora
The faucet water supply has chlorine as well as various other ingredients to keep it tidy, yet these additives are harmful to fish, so you need to always use a water conditioner made for aquariums.
You intend to make certain the Chili Rasbora is kept in a college of at least 6. Less than that and they will not be happy– they are suggested to be together. You can house two Chili Rasbora per gallon, so 6 fish would be acceptable for a 5-gallon container.
Security is the most essential thing when it concerns keeping chili rasboras, so the more small water adjustments you can do, the far better. Naturally, just how much water you alter at any type of provided time totally depends on your water problems in the container as well as out of the faucet.
Go for somewhere in the 10% two times a week or 15% once a week array to keep things extremely stable for them. If your storage tank, as well as your tap, aren’t near each other, go for even smaller-sized, extra regular water adjustments. Certainly, you’ll need a quality tap water conditioner (or dechlorinator), and a bit of fish tank salt never ever hurts, either.
With these individuals, it’s not as much concerning eliminating waste as it has to do with keeping the chemistry in their tank stable. If it swings excessively or as well quickly, you’re likely to see die-offs or at least an episode of disease.
Mentioning illness, everything you’ll require to treat the usual chili rasbora conditions is listed here.
lighting & Filtering
Chili rasboras like lowered lighting. You can attain this in a couple of means– the simplest being drifting plants. If you’re trying to find a little bit more control over the lighting entering into your container, there are some excellent adjustable lights on the market that are plug-and-play, as well as I’ve consisted of a few of those listed below for you.
When it comes to filtering, these little guys can conveniently resist the majority of levels of current, so you’ll desire your sponge filter to be rather low.
Sufficient to develop a little of surface agitation and water activity suffices. If you don’t know where to start with sponge filters as well as air pumps, I’ve listed the most effective of those listed below for you as well.
Storage Tank Mates for Chili Rasboras
Finding container friends for Chili Rasboras is both very easy and hard because they are so tiny! Also, fish that you would not think of as problematic, like Tiger Barbs, can be daunting and even hostile towards nano fish.
The very best storage tank mates by far are various other Chili Rasboras They are often eye-watering pricey for such little fish but you definitely require 6-12 minimum. Afterward, stay with other nano fish as well as invertebrates.
A number of the best nano fish originated from comparable environments and hence share the exact same water top quality requirements. Sparkling Gouramis are a fantastic option, as are smaller Tetras like Neons. Endler’s Livebearer (Poecilia winger) is a Guppy relative that does not such as waters fairly so acidic yet will certainly do fantastic at pH 5.5+.
Adhere to peaceful, soft water fish smaller sized than 2 1/2 inches in size. Luckily, there are actually lots of ideal fish in the fish tank pastime! Betta fish are exceptional tank mates for Chili Rasboras.
They have a track record of being “indicate” however Bettas actually save their hostility for each and every various other, specifically other men. They tend to neglect anything that isn’t a Betta, though they might chase Guppies as well as other vibrant, long-finned fish. Bettas also prosper in acidic, warmed fish tanks abundant in plant tannins!
The most awful container mates are huge, predatory, or territorial fish. Also, fish that are normally tranquil, like Angelfish, will gladly snack on a little Chili Rasbora once it gets a bit bigger. As well as fish above 3 inches in size are just as well daunting for nano fish even if they’re completely peaceful.
Nearly all invertebrates are fine with Chilis except Crabs as well as Crayfish of all kinds, which are opportunistic killers. They will happily seize a Rasbora that’s resting, unwary, or sick.
They make fine container friends for the similarly tiny dwarf shrimp species, especially the much more fragile Bee Shrimp (Caridina cantonensis).

Diet Chili Rasbora
Although they are omnivores, Chili Rasboras choose a meat-eating diet plan. Offer them a selection of flakes, pellets, and also freeze-dried, fresh, or icy protein resources like bloodworms as well as chopped micro worms.
To make sure the most effective shade and health of your Chili Rasbora, make certain you provide diverse sources of nourishment. Be conscious not to overfeed these fish– they are really small as well as can get ill if they consume excessively, as well as additionally the more they consume, the even more waste they create, which can unclean the water as well as make them sick.
One final thing to remember is that because of their nano size, they require all food cut and pulverized. Flakes, for example, should be crushed to powder form.
Feeding chili rasboras isn’t difficult if you locate food that can suit their mouth, which can be a little difficult if you’re not utilized to little fish. Some great alternatives for online food are infant brine shrimp, little daphnia, microforms, vinegar eels, wingless fruit flies, little bloodworms, mosquito larvae, and also anything you would usually feed to the small fry.
Frozen food is a little tougher considering that most of the alternatives are a bit large. You can try chopping bloodworms right into smaller-sized pieces or searching for icy baby saltwater.
Plants & Substrate
Live plants are also necessary to keeping Chili Rasboras energetic and healthy. They absorb nitrate, co2, and also various other harmful compounds, release oxygen, give color, and also look fabulous.
Discovering the right plants can be a little bit of a battle though because not all plants flourish in temperature levels past 78 ℉. Want to plants that do well in Angelfish and Discus storage tanks, two other equatorial blackwater fish that like points hot.
Amazon Swords, Java Brush, and Java Moss offer the cover Chili Rasboras need and are all very easy to grow. Java Fern and also Java Moss are excellent low-light plants however several other tropical species require full-spectrum lights to flourish.
When it involves substrates, Chili Rasboras aren’t too choosy. They are surface to midwater dwellers and also much as well tiny to dig or root out designs.
I suggest selecting sand or gravel; whichever works ideal for your plants and also your individual aesthetic.
If you can, I likewise recommend mixing in peat moss, sphagnum moss, or making use of a dirt base layer. Both of these will certainly not just boost plant growth but are one more slow-release resource of tannins that will certainly buffer your water in the direction of acidity.
Stick to a darker substratum. Brown is great; black is better. The comparison it provides to the eco-friendly plants, as well as intense red as well as black tones of your Chili Rasboras, will truly help your fish tank pop, also from a range!
Paler substrates often tend to wash out fish shades. Your Rasboras will discolor to keep from sticking out, lest predators choose them off.
Breeding Chili Rasbora
When they are ready to breed, the male Chili Rasboras transform a brighter red, so you can tell them besides the woman. On top of that, the black and also red markings on their dorsal and also tail fins end up being darker.
Females, on the other hand, will certainly look rounder as well as plump because they bring eggs.
Pro tip: Beware since the male Chili Rasboras can get a little territorial at breeding time, and they might combat, so you require to make sure that you have enough space for them to have their own little location.
You may see the male Nanos flaunting to obtain the woman’s interest. If he gets it, the female will lay a small number of eggs that she spreads on the container’s bottom.
And that is where the parenting finishes. Neither the male nor the women Chili Rasbora proactively take care of their eggs in any way. Actually, they have been known to cannibalize their very own eggs.
It’s a type of enjoyment to see them generating– they resemble they are going after each other around the tank. The male and women Chili Rasbora can be kept in the reproduction tank for 3 or 4 days and afterward they ought to be moved back to the major storage tank.
If you leave them in the reproduction container for longer than that, the Chili Rasbora fry is at risk.
Remember that Chili Rasbora is particularly sensitive to water modifications, so if you are making use of a reproduction container, you have to make sure that the temperature level, slow-moving, pH, as well as solidity is consistent in both containers; otherwise, you are most likely to shed the fish in the transfer as they can not tolerate the instability.
If your residence fish tank is dense sufficient, the fry may have enough cover to survive despite the risk of other fish in the storage tank having them for a midnight snack (never mind their very own moms and dads!) Nevertheless, if you are intending to breed the Chili Rasboras in earnest, you must set up a different breeding tank.
They spawn quite continuously, so in a different breeding tank, you have the opportunity to provide the fry a combating opportunity to live. You can feed the fry infusoria and paramecium until they can take care of larger foods.
To produce the very best equilibrium for breeding, you will certainly require 1 to 2 women for every single male in the container, as well as you’ll need males that are leading.
