Harlequin Rasbora 2.5cm (Group of 10)

The Harlequin Rasbora (Trigonostigma heteromorpha) is one of the most popular and enduring community fish in the freshwater hobby. Displaying a warm copper-orange body with a striking black triangular patch on the rear half, a school of Harlequins moving together under aquarium lighting is a classic and beautiful sight. Hardy, peaceful, and easy to keep, they are an ideal choice for both beginners and experienced aquarists alike.
