Rasbora and Danio are genera of fish in the Cyprinidae family so they are native to freshwater habitats in South and Southeast Asia, as well as southeast China.
As they normally adapt to different water conditions are a great add for community tank adding a lot of movement to the tank.
Choice of decor is not as critical as water quality although this species does look particularly effective in a well-planted tank with a dark substrate. To see it at its best a biotope-style set-up can also make an interesting project. A soft, sandy substrate is probably the best choice to which can be added a few driftwood roots and branches, placed in such a way that plenty of shady spots are formed. If you can’t find driftwood of the desired shape common beech or oak is safe to use if thoroughly dried and stripped of bark.
