The Micro Rasbora (Boraras spp.) is a small, peaceful freshwater fish belonging to the Cyprinidae family. Native to the slow-moving, shaded forest streams and peat swamps of Southeast Asia, these charming fish are highly sought after for their vivid coloration, tiny size, and calm temperament.

🧡 Appearance & Behavior

Micro Rasboras are known for their striking red, orange, or golden hues with contrasting black markings depending on the species (Boraras brigittae, Boraras maculatus, Boraras urophthalmoides, etc.).
They are schooling fish, best kept in groups of 8 or more, which allows them to display their natural social behavior and vibrant colors.

🌱 Tank Setup

Micro Rasboras thrive in heavily planted aquariums that mimic their natural habitat.
A gentle filtration system and dim lighting are ideal, as these fish prefer calm waters. Floating plants and fine-leaf vegetation provide excellent cover and reduce stress.

💧 Water Conditions

They prefer soft, slightly acidic water and appreciate the stability provided by regular maintenance. Weekly partial water changes (20–25%) help maintain optimal health.

🍽️ Feeding

Being micro-predators, Micro Rasboras feed on small invertebrates in the wild. In captivity, they readily accept:

• High-quality micro pellets

• Crushed flakes

• Frozen or live foods (daphnia, cyclops, brine shrimp)

Feed small portions 2–3 times daily.

🐣 Breeding

Breeding Micro Rasboras is possible in a well-established, peaceful setup. Use fine-leaf plants or spawning mops for egg scattering. Parental care is absent, so remove adults post-spawning to protect the eggs.

🌈 Ideal Tankmates

These tiny, non-aggressive fish do best with other peaceful nano species:

• Pygmy Corydoras

• Small Tetras (Ember Tetra)

• Shrimp (Amano, Cherry)

• Snails

Avoid larger or fin-nipping fish.
