Common Name: Mosquito Rasbora
Scientific Name: Boraras brigittae
Origin: Borneo (Southeast Asia)
Maximum Size: 1.5 – 2 cm (0.6 – 0.8 inches)
Tank Parameters:
pH: 6.0 – 7.0
gH: Soft (3 – 8 dGH)
Temperature: 22 – 28°C (72 – 82°F)
Tank Size: Minimum 5 gallons (ideal in groups of 10+)
Temperament: Peaceful, shy, schooling fish
Diet: Omnivore – micro-pellets, baby brine shrimp, crushed flakes
Difficulty: Easy to Moderate
Mosquito Rasboras are peaceful micro fish perfect for nano tanks, planted aquariums, or blackwater biotopes. They thrive in soft, slightly acidic water and love swimming in groups. Best kept in schools of 8 or more to display natural shoaling behavior and reduce stress.
They scatter eggs in fine-leaved plants or moss. Breeding can occur in soft, warm water with subdued lighting, though fry are tiny and require infusoria or microfoods.
Other micro-rasboras (like Phoenix or Strawberry Rasbora)
Dwarf shrimp (e.g., Cherry, Blue Velvet, Yellow)
Otocinclus, small Corydoras, or Ember Tetras
Avoid large or aggressive fish
Due to their tiny size and sensitivity, avoid strong currents or sudden parameter swings. A heavily planted tank with soft lighting will bring out their intense red coloration and contrasting black markings. Ideal for aquascaped setups.
Boraras maculatus naturally come from soft, acidic blackwater environments.
If your water is too hard or alkaline, it can dull their colors.
