One of the most popular community fish, known for its copper-orange body and bold black triangular patch that extends across much of the rear half of the body. Growing to about 4–5 cm (1.5–2 inches), it is hardy, peaceful, and best kept in schools where its natural shoaling behavior can be appreciated.
It can be distinguished from the Glowlight Rasbora (Trigonostigma hengeli) and Lambchop Rasbora (Trigonostigma espei) by its larger size, deeper body shape, and much larger black wedge marking. Glowlight Rasboras have a much smaller wedge outlined by a brilliant orange stripe, while Lambchop Rasboras display a narrower, more sharply angled wedge that resembles the shape of a lamb chop. The Harlequin's bold, solid triangular patch is the largest and most prominent of the three species.
