Appearance and identification
Compared with emerald dwarf danios, this fish has an orange line and shorter bars; emerald dwarfs show stronger blue-green bars and a tail-base spot.
Same-species behaviour
Keep at least 8–10; male hierarchies make refuge space important even in a group.
Space requirements
Use an 80 × 30 cm base.
Diet and feeding
Offer small prepared foods and live or frozen foods, making sure subordinate fish get enough.
Compatibility limits
Check predation, feeding competition, space and water needs before choosing tankmates.
Aquarium environment
Plants and wood can break sight lines while leaving a swimming lane; planted layouts do not need strong current.
