Stunning in planted tanks
Peaceful community fish
Green Kubotai Rasboras (Microdevario kubotai) are tiny, active nano fish with unusually bright neon yellow-green coloration. Adults remain under an inch and are especially visible in planted aquariums.
They do best in mature, clean, well-oxygenated water with moderate flow and a proper social group.
Care Notes
Provide open mid-water swimming space, plant cover, and moderate flow. Keep water clean and stable.
Feed small foods once or twice daily and keep at least 10 for more confident behavior.

Species Spotlight
Why We Love This Fish
01
True Neon-Green Color
Few freshwater fish show the same bright yellow-green body color.
02
Active Mid-Water Schooler
A proper group creates continuous movement through the center of a planted tank.
03
Good With Adult Shrimp
Generally compatible with adult shrimp, though very small shrimplets may still be at risk.
Community Tank
Compatible Tank Mates
These nano fish coexist well with shrimp and other peaceful invertebrates.
Keep at least 10 in a planted 10-gallon or larger aquarium with open mid-water space and moderate flow. In our experience, larger groups are more confident and create a much stronger display.
