Dwarf Spotted Rasbora (Boraras maculatus) is a small and colorful freshwater fish that is perfect for nano and planted aquariums. Native to the slow-moving blackwater streams and peat swamps of Southeast Asia, these tiny fish are known for their vibrant colors, peaceful nature, and active schooling behavior. Their small size and striking appearance make them a favorite choice for aquarists who enjoy maintaining natural, heavily planted tanks.

Appearance
Dwarf Spotted Rasboras reach only about 0.6–0.8 inches in length, making them one of the smallest freshwater fish available in the hobby. They have a translucent to reddish-orange body with distinct black spots along the midsection, which gives them their name. Males tend to be more brightly colored, while females are slightly larger with a rounder body. Their delicate beauty stands out best in well-planted tanks with dark substrates.

Behavior
These rasboras are peaceful schooling fish that thrive when kept in groups of at least 8–10 or more. In a school, they feel more secure, display brighter colors, and show more natural behavior. They are active swimmers that typically occupy the middle and upper levels of the tank. Their calm and gentle temperament makes them an excellent choice for community tanks with other small species.

Tank Requirements
Dwarf Spotted Rasboras do well in small aquariums starting from 5 gallons, but larger tanks allow for bigger schools and more natural displays. They prefer heavily planted aquariums with plenty of hiding spots, driftwood, and leaf litter that replicate their natural habitat. A dark substrate and subdued lighting help bring out their vivid coloration.

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

Since they come from blackwater environments, clean, stable water conditions are vital. Gentle filtration and regular water changes will ensure their health and well-being.

Diet
Dwarf Spotted Rasboras are micro-predators in the wild, feeding on tiny insects, zooplankton, and larvae. In captivity, they can be fed a diet of crushed flakes, high-quality micro-pellets, and small live or frozen foods such as baby brine shrimp, daphnia, and microworms. Providing a varied diet enhances their colors and keeps them active and healthy.

Tank Mates
These rasboras are best housed with other small, peaceful species such as Chili Rasboras, Celestial Pearl Danios, Ember Tetras, and dwarf shrimp. Avoid housing them with larger or aggressive fish that may view them as food.

Breeding
Breeding Dwarf Spotted Rasboras in captivity is possible but requires a separate breeding tank with dense plants or spawning mops. They are egg scatterers, and adults may eat the eggs if not separated. The fry are very small and require infusoria or other microscopic foods before being transitioned to baby brine shrimp.

Conclusion
The Dwarf Spotted Rasbora is a tiny yet vibrant fish that brings life and beauty to nano and community aquariums. Their peaceful schooling nature, bright colors, and compatibility with planted tanks make them a wonderful choice for aquarists seeking a lively but delicate species. With proper care and water stability, these little gems can thrive and become a highlight of your aquarium.
