General: The Indonesian chili rasbora is an endemic species, native to Borneo. Naturally, the chili rasbora occupies "blackwater" (5.5 to 7.5 pH, and very soft water) wetlands of Borneo, where they feed on microinvertebrates. They make great additions to the peaceful community nano aquarium!

Dimorphism: Once mature, the chili rasbora male will become slightly brighter in coloration. The female will retain her original colors. The female chili rasbora will take on a more gravid appearance when ready to reproduce.

Fecundity: Acidic, soft water conditions are critical when attempting to breed chili rasbora. Floating plants as well as an optimal diet will promote reproductive behaviors. Initially, fry can be given infusoria and later on can be switched over to live baby brine shrimp.

Water Chemistry: 72-82° F, KH 4-8, pH 5.5-7.5

Aquarium Diet: Chili rasboras are omnivores and will accept brine shrimp, blackworm, fish flake, small omnivore pellets, and spirulina flakes.

Compatibility: The chili rasbora is typically compatible with other small rasbora species such as the green neon rasbora (Rasbora kubotai), danios such as the galaxy danio (Danio margaritatus), small tetras such as the neon tetra (Paracheirodon innesi) and ember tetra (Hyphessobrycon amandae), hatchetfish such as the common hatchetfish (Gasteropelecus sternicla) and Corydoras such as the pygmy corydoras (Corydoras pygmaeus).
