About this fish

Coppery color and a distinctive body pattern make Copper Harlequin Rasboras a warm accent in a planted tank. Their coordinated swimming is best enjoyed as a group.

Is this right for me?

Plan for a group of fish, enough swimming room, and a tank that has completed its cycle. Check the needs of the fish you already keep.

Getting your tank ready

Use an aquarium that has completed its cycle: helpful bacteria in the filter must be established to break down animal waste. A newly filled tank is not ready for animals just because the water looks clear. Keep water conditions steady. Introduce fish gradually to the new tank's water, and provide plants for cover as well as open swimming space. Keep this fish in a group.

Keeping it with other animals

Choose gentle fish of a similar size. Fish may eat baby shrimp, even when plants provide hiding places.

What you get

Choose the quantity offered in the product options. Natural coloration and individual size vary.
