Kubotai Rasbora

Kubotai Rasbora

The Kubotai Rasbora (*Microdevario kubotai*) is a diminutive and vibrant freshwater fish native to Southeast Asia, particularly Thailand and Myanmar. Renowned for its striking neon green coloration, this species adds a lively splash of colour to aquariums.

Physical Characteristics:

• Size: Kubotai Rasboras are exceptionally small, typically reaching up to 2 cm (0.8 inches) in length.
• Coloration: They exhibit a vivid neon green hue that intensifies under proper lighting, making them a visual highlight in any tank.
• Fins: Their fins are relatively short and streamlined, complementing their petite size and active swimming behaviour.
• Shape: The body is slender and elongated, characteristic of the Rasbora genus.

Behaviour:

• Temperament: Kubotai Rasboras are peaceful and social, thriving in groups and exhibiting minimal aggression.
• Activity Level: They are active swimmers, often seen darting through the water in schools, adding dynamic movement to the aquarium.
• Community Behaviour: Their gentle nature makes them ideal companions for other small, non-aggressive species.

Aquarium Care:

• Tank Size: A minimum of 10 gallons (approximately 38 litres) is recommended for a small group, though larger tanks are preferable for more stable water conditions.
• Water Parameters:
  • Temperature: Kubotai Rasboras thrive in warm water, with an ideal temperature range of 22°C to 27°C (72°F to 80°F).
  • pH: They prefer slightly acidic to neutral water, with a pH range of 6.0 to 7.5.
  • Hardness: Soft to moderately hard water, with a general hardness (GH) of 4-8 dGH, is ideal.
• Tank Setup:
  • Substrate and Decorations: A well-planted tank with dense vegetation and subdued lighting mimics their natural habitat. Floating plants can provide additional cover and diffuse light.
  • Filtration: A gentle filtration system is recommended, as strong currents can stress these small fish. Regular water changes (about 20% weekly) are essential for maintaining a clean and healthy environment.

Diet:

Kubotai Rasboras are omnivorous and require a varied diet to thrive. Their diet should include:

• Pellets: High-quality micro-pellets designed for small tropical fish should form the staple of their diet.
• Live or Frozen Foods: Offer live or frozen foods such as brine shrimp, daphnia, and micro-worms to provide essential protein and variety.
• Vegetable Matter: Including finely chopped vegetables or algae-based foods can help ensure a balanced diet.

Tankmates:

Due to their small size and peaceful nature, Kubotai Rasboras are best kept with other small, non-aggressive species. Suitable tankmates include:

• Small Tetras: Such as Neon Tetras or Ember Tetras.
• Peaceful Rasboras: Like Harlequin Rasboras.
• Bottom-Dwellers: Corydoras catfish or other peaceful bottom-dwellers.

Avoid housing them with larger or aggressive species, as they may become prey or experience undue stress.

Breeding:

Breeding Kubotai Rasboras in captivity can be challenging due to their small size and specific requirements. However, under optimal conditions:

• Breeding Setup: A separate breeding tank with shallow water (about 10-15 cm or 4-6 inches) is ideal. The water should be warm (around 24°C to 26°C or 75°F to 79°F) and slightly acidic (pH 6.0-6.5).
• Spawning Behaviour: The male will court the female and guide her to the spawning site, often among dense vegetation. After spawning, the male may guard the eggs until they hatch.
• Fry Care: Once the fry are free-swimming, they can be fed with infusoria or newly hatched brine shrimp. The parents should be removed to prevent them from eating the fry.

Special Considerations:

• Water Quality: Regular monitoring and maintenance of water quality are crucial for the health of Kubotai Rasboras.
• Shy Nature: These fish can be shy, particularly in brightly lit tanks. Providing plenty of hiding spots can help them feel more secure.
