Aquascaping Tips:
A dark substrate and lush aquatic plants such as moss, Java fern, or Rotala will highlight their fluorescent green body. Floating plants can help diffuse light, creating a natural and secure environment.

Compatible Tank Mates:

Kubotai Rasboras are extremely peaceful and thrive in groups. Their tiny size means they’re best housed with similarly sized and non-aggressive species.

Ideal companions include:

• Chili Rasboras
• Ember Tetras
• Celestial Pearl Danios
• Dwarf Pencilfish
• Pygmy Corydoras
• Otocinclus
• Shrimp (e.g., Amano or Neocaridina)

Avoid housing with large fish or boisterous tankmates that might outcompete them or cause stress.

Feeding Habits:

Kubotai Rasboras are micropredators and will eat small floating and suspended foods.

• Staple Diet: Micro pellets, powdered flakes
• Supplements: Live or frozen foods like daphnia, baby brine shrimp, micro worms
• Feeding Frequency: 1–2 times per day in small, manageable portions

Their small mouths mean food should be finely crushed or appropriately sized.

Care and Maintenance:

Though small, these rasboras do best in stable, high-quality conditions. Proper care ensures their colors stay vibrant and health stays optimal.

• Weekly water changes (20–30%)
• Stable temperature and pH
• Keep in groups of 6 or more for social comfort and visual appeal
• Provide swimming space despite their small size

Breeding Information:

Breeding Kubotai Rasboras can be done with attention to detail:

• Use a separate breeding tank with soft, warm water (~26–27°C)
• Provide fine-leaved plants or spawning mops
• Feed breeders live food to induce spawning
• They scatter eggs among plants; adults should be removed after spawning
• Eggs hatch within 24–48 hours
• Feed fry infusoria, then move on to baby brine shrimp

Summary:

The Kubotai Rasbora is a vibrant, peaceful, and active nano fish that brings electric green motion to any planted aquarium. Best displayed in groups, they add a dazzling contrast to aquascapes and pair beautifully with other gentle nano species. Ideal for both newcomers and seasoned aquarists, this species is a glowing example of nature’s brilliance in miniature.
