Strawberry Rasbora (Boraras brigittae “Strawberry”) is a small, colorful freshwater fish that is highly prized for its brilliant red coloration and peaceful nature. Originating from the slow-moving blackwater streams and peat swamps of Southeast Asia, particularly Borneo, these tiny fish are perfect for nano aquariums, planted tanks, and community setups with other small, non-aggressive species. Their vibrant color and active schooling behavior make them a favorite among aquarists.

Appearance
Strawberry Rasboras are tiny fish, typically growing to about 0.6–0.8 inches in length. Males are usually the most colorful, displaying a rich red body with a slight orange hue and a faint black horizontal stripe along their sides. Females are slightly larger and paler but still attractive. Their small size and vivid color make them ideal for creating a lively, eye-catching display in planted aquariums.

Behavior
These fish are peaceful, active, and thrive in groups. A school of at least 10 individuals is recommended to ensure they feel secure and display their best colors. They spend most of their time swimming in the mid to upper levels of the tank, often interacting with each other in synchronized movements. Their calm nature makes them excellent community fish when housed with other small, non-aggressive species.

Tank Requirements
Strawberry Rasboras do well in small to medium-sized aquariums, starting at 5–10 gallons for a small school, although larger tanks are better for showcasing groups. A well-planted tank with driftwood, leaf litter, and hiding spots helps mimic their natural blackwater habitat. Dark substrates enhance their red coloration and make them stand out.

Water Parameters
Temperature: 72–82°F
pH: 4.0–7.0 (slightly acidic preferred)
Water Hardness: Very soft to moderately hard

Maintaining stable and clean water is essential, as these fish are sensitive to poor water quality. Gentle filtration and regular water changes will keep them healthy and vibrant.

Diet
Strawberry Rasboras are micro-predators that feed on tiny live foods in the wild, including zooplankton and insect larvae. In captivity, they accept high-quality micro-pellets, crushed flakes, and small frozen or live foods such as daphnia, microworms, and baby brine shrimp. A varied diet promotes vibrant coloration and active behavior.

Tank Mates
Due to their peaceful nature, Strawberry Rasboras are best kept with other small, gentle species such as Celestial Pearl Danios, Ember Tetras, and other nano fish. They can also coexist with dwarf shrimp and snails. Avoid aggressive or larger fish that could outcompete or harm them.

Breeding
Breeding Strawberry Rasboras in captivity is possible but challenging. They are egg scatterers and prefer heavily planted tanks or spawning mops. Fry are very small and require microscopic foods such as infusoria before transitioning to baby brine shrimp.

Conclusion
Strawberry Rasboras are tiny, vibrant, and peaceful fish that add color and activity to any freshwater aquarium. Their striking red hue, schooling behavior, and compatibility with other small species make them perfect for nano tanks and planted aquariums. With proper care, stable water, and a well-planted environment, Strawberry Rasboras can thrive and become a captivating highlight of your aquarium.
