Chili Rasbora’s mannerisms

This is the fish for you if you want a fish with a calm demeanour. The chilli rasbora is a calm schooling fish.

They spend the majority of their time swimming together in the tank’s middle and upper regions.

If you have these in your tank, they will occasionally investigate the bottom hiding areas and grassy areas.

How many are there per gallon?

Because these fish are hesitant, keeping them together encourages them to form natural schooling groups.

You should try to build a group of at least six people. These fish are frequently sold in bunches of three to twenty-four on the internet.

In aquariums as little as five gallons, a school of up to six fish can be accommodated. If you wish to keep living plants and/or other species, you’ll need a bigger tank.

A better environment for any fish is one with more swimming areas and hiding sites.

The setup of the tank for chili rasbora

The chile rasbora flourishes in a species-only tank or one where they are the only inhabitants.

This is simple to perform without a large budget due to their modest size. You can keep a small school of them in a five-gallon tank.

Chili Rasbora’s water parameters

The most difficult aspect of raising chile rasboras is water sensitivity.

The water in their natural habitat is relatively gentle. Maintain a water hardness of 3 to 12 dKH in your tank.

The pH of the water should be kept low, ideally between 4.0 and 5.0; however, the fish can thrive in water with a pH of 6.0 to 7.0.

To begin, combine distilled or reverse osmosis water with tap water. It is not recommended since the mineral and chlorine concentrations in tap water are too high for the chile rasbora.

A water filter will not assist because it adds a lot of sodium to the water.

To balance the pH and colour the water slightly, add peat moss, peat pellets, alder cones, or Indian almond leaves.

Because of the tannins generated by the plant matter, the resulting water, nicknamed blackwater, should be clear but tannic in colour.

Before you put your fish in the water, make sure it’s the right pH and hardness. Keep an eye on the levels with test kits available at most shops.

Maintain a temperature of 68 to 82 degrees Fahrenheit (20 to 28 degrees Celsius), with a temperature of 74 degrees being optimum.

A heater is a wonderful investment if you keep your fish in a nano tank because the small volume of water can quickly change temperature owing to temperature fluctuations in the surrounding air.

Using a siphon, clean the gravel in your tank on a regular basis. To avoid the buildup of undesirable ammonia and nitrite, change a portion of the water once a month.


For the chile rasbora, filtration and illumination are also vital.

The flow of whichever filter you install should be set as low as possible because this species is accustomed to mild waters in its natural habitat.

Plants or other decorations can be used to break up the flow of water, and the filter should be cleaned every few weeks. To simulate the natural environment, low lighting is ideal.

If included, the planted zones and floating plants will help soften the light and create a more pleasant environment for your chilli rasboras.

The Chili Rasbora Tank’s Companions

Avoid exposing the tank to direct sunlight for long periods of time by utilizing a dimmable LED aquarium light.

A lamp with a timer can assist you in maintaining an 8 to 12-hour cycle.

A species-only tank is the optimal tank setup for chilli rasboras, as previously stated. These wary, peaceful fish prefer to congregate with other mosquitoes.

They’ll get along swimmingly in a communal tank if kept with other small, docile fish.

If you have any larger fish, mosquito rasboras may become food!
