Overview

Rasboras are a popular staple for small aquascapes and nano tanks due to their tiny adult size. They are orange or red in color, hence their name. Dominant males will be a brilliant red, while lesser males, females and juveniles will be less bold looking.

They will appreciate a dimly lit tank, naturally being blackwater fish. Live plants, both floating and anchored, create an optimal environment for them. Indian almond leaves can also be scattered along the bottom of the tank. They should only be added to established tanks with stable water conditions and are highly susceptible to changing water chemistry.

They should be fed high quality flakes or pellets as well as live and frozen daphnia.
