Compatibility

Harlequin Rasboras are an exceptional addition to your tank and are known as one of the most peaceful aquarium fish. This fish thrives well in a school, and it is recommended to have six or more for best display. These fish like planted aquariums with lots of open spaces to swim.

Breeding

It is difficult to distinguish male or female in this fish, a small indicator of sex is that the male is slenderer. As this fish requires soft and acidic water to breed it can be quite a challenge. The eggs produced are adhesive and will grip to plants around the tank.

Colour and Varieties

The Harlequin Rasbora has a distinguishable black triangular wedge that goes from the lateral line to the caudal peduncle then to the stomach. This is offset by its base colour of red.
