The Glowlight Rasbora and Harlequin Rasbora, while visually similar, have distinct characteristics. Glowlight Rasboras are smaller, typically reaching about 3.8 cm in length, and are recognized by their slender bodies and a prominent horizontal orange stripe extending from mid-body to the tail. Their bodies are more translucent, with the stripe glowing iridescently under light. In contrast, Harlequin Rasboras are slightly larger, growing up to about 5 cm, and are notable for their deeper, more opaque orange or reddish hue, along with a distinctive black, triangular patch near the tail. These variations in size, body color, and specific markings are key for distinguishing between the two species.
