The Chili Rasbora, scientifically known as Boraras brigittae, is a tiny yet stunning freshwater fish belonging to the Cyprinidae family. Native to the slow-moving, peat-swamp forests of Southwest Borneo, Indonesia, this species is adored by aquarists for its vibrant red coloration and delicate size. Chili Rasboras are perfect for nano aquariums, where their bright red hues can create a striking contrast against lush green plants. These fish typically grow to about 0.8 inches (2 cm) in length and can live for 4-6 years in captivity when provided with proper care.
Habitat and Tank Requirements:
In their natural habitat, Chili Rasboras are found in acidic, tannin-rich waters that are heavily shaded by dense forest canopies. The water in these environments is soft and highly acidic, often stained dark by decomposing organic matter. To replicate these conditions in a home aquarium, it’s important to provide a tank with appropriate water parameters and a setup that mimics their natural environment.
Tank Size and Water Parameters:
| PARAMETER | RECOMMENDED |
|---|---|
| Tank Size | Minimum 20 litres |
| Temperature | 72-82°F (22-28°C) |
| pH | 4.0-7.0 (Ideal: 5.0-6.5) |
| Hardness | Soft water, 1-5 dGH |
This table provides the optimal water conditions for keeping Chili Rasboras healthy and displaying their vibrant colors. These fish thrive in well-maintained tanks with stable water parameters, particularly those that replicate the soft, acidic conditions of their natural habitat.
Chili Rasboras thrive in tanks with a soft, dark substrate, such as sand or fine gravel, which helps bring out their vivid red coloration. The tank should be densely planted with live plants, including floating varieties, to create shaded areas and simulate the dark, forested waters they come from. Driftwood and leaf litter can be added to further replicate their natural environment, releasing beneficial tannins into the water. A gentle filter is recommended to maintain water quality without creating strong currents, as these fish prefer calm waters.
