How do you know if a tiger barb is male or female?

1. Size: Male tiger barbs are generally larger than females, with a more robust body shape. Females tend to be smaller and more slender.

2. Coloration: Male tiger barbs tend to have more intense and vibrant coloration, especially during breeding season. They may have a deeper red or orange hue, while females are typically more pale and subdued in color.

3. Body Shape: Male tiger barbs have a broader and more muscular body shape, while females have a rounder and fuller belly.

4. Fins: The dorsal fin of a male tiger barb is usually longer and more pointed compared to the female's, which is shorter and more rounded. Additionally, the male's anal fin may be slightly concave, while the female's is usually straight or convex.

5. Behavior: During the breeding season, male tiger barbs may display aggressive behavior towards each other, and they often chase females. Females may become plumper and more rounded in the belly when carrying eggs.

It's important to note that these traits can vary among individual tiger barbs, so it's not always possible to determine the sex with 100% accuracy. However, by observing these characteristics, you can make a good estimate of a tiger barb's sex.
