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

- Shrimp (e.g., Amano or Neocaridina)
Avoid housing with large fish or boisterous tankmates that might outcompete them or cause stress.

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:
