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

- 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.
