Green Kubotai Rasbora: The Bright Jewel of Nano Tanks

The Green Kubotai Rasbora (Microdevario kubotai), also known as the Neon Green Rasbora, is a dazzling nano fish that stands out for its electric green coloration. This small, peaceful species is ideal for planted aquariums and adds a vibrant splash of color, making it a favorite choice among aquarists who appreciate tiny, energetic fish.

Origins of the Green Kubotai Rasbora

The Green Kubotai Rasbora is native to the clear, slow-moving waters of streams and rivers in Southeast Asia, particularly in Thailand and Myanmar. These fish inhabit densely vegetated areas where they can find plenty of cover and a variety of food sources. In the wild, they live in shoals, making them a stunning sight as they dart together through the greenery.

Appearance

The Green Kubotai Rasbora is most recognizable for its bright neon green body, which can shimmer in different shades of green and yellow depending on the lighting. Their slender, streamlined shape and small size (growing up to 1-1.5 inches or 2.5-4 cm) make them a perfect fit for nano and community aquariums.

The fish has:

• A slender, elongated body with a metallic green sheen.
• Translucent fins, which give them a delicate, almost ethereal appearance.
• A small, slightly upturned mouth, adapted for picking at tiny food particles.

Tips for Keeping Green Kubotai Rasbora in Aquariums

1. Tank Size and Environment:
   • Despite their small size, Green Kubotai Rasboras are active swimmers and do best in a minimum of a 10-gallon tank, especially if kept in a group.
   • They thrive in well-planted tanks with plenty of live plants, such as Java Fern, Anubias, and Hornwort. Floating plants like Duckweed or Frogbit can help diffuse the light and make the fish feel more secure.
   • Provide open swimming space along with shaded areas created by plants and decorations.
2. Water Parameters:
   • Temperature: 72-78°F (22-26°C)
   • pH: 6.0-7.5 (slightly acidic to neutral water is preferred)
   • Water Hardness: 2-12 dGH
   • Regular water changes and a well-maintained filter are essential to keep the water quality high, as Kubotai Rasboras are sensitive to poor water conditions.
3. Diet and Feeding:
   • Green Kubotai Rasboras are micro-predators, feeding on tiny invertebrates, larvae, and plant matter in the wild.
   • In the aquarium, offer them a variety of high-quality micro foods like crushed flakes, micro pellets, and live or frozen foods such as daphnia, brine shrimp, and microworms.
   • Feed them small amounts twice a day, as they have tiny mouths and prefer smaller food particles.

Good Tank Mates for Green Kubotai Rasbora

Green Kubotai Rasboras are peaceful and social, best kept in groups of at least 6-10 individuals. Their shoaling behavior makes them more confident and brings out their best colors. They are great community fish and can be housed with other small, non-aggressive species.

• Compatible Tank Mates:
  • Other Rasboras (Chili Rasbora, Harlequin Rasbora): They share similar water requirements and temperament.
  • Small Tetras (Neon Tetras, Ember Tetras): Peaceful and colorful, they add to the visual appeal.
  • Dwarf Corydoras (Pygmy Corydoras, Salt and Pepper Corydoras): Bottom-dwellers that help keep the tank clean.
  • Shrimp (Amano Shrimp, Cherry Shrimp): Non-aggressive and beneficial for the ecosystem.
  • Snails (Nerite Snails, Mystery Snails): Great for algae control and safe with Rasboras.
• Avoid:
  • Larger or aggressive fish like Cichlids, which may see the Green Kubotai Rasbora as prey.
  • Fin-nipping species, as they might stress or harm these delicate fish.

Breeding Green Kubotai Rasbora

Breeding Green Kubotai Rasboras in a home aquarium can be challenging but rewarding. They are egg scatterers, releasing their eggs among fine-leaved plants or moss. To encourage breeding:

• Set up a separate breeding tank with plenty of plants like Java Moss for egg-laying.
• Condition the fish with live or frozen foods for a few weeks before breeding.
• Once eggs are laid, remove the adults to prevent them from eating the eggs.
• The eggs will hatch in 24-48 hours, and the fry can be fed infusoria or powdered fry food until they are large enough to accept baby brine shrimp.
