How tall can piranhas be?

Piranhas can vary in size depending on the species, but they typically range from about 6 to 12 inches in length. The largest species, such as the Red-bellied piranha, can grow up to 12 inches long, while some exceptional individuals may reach up to 20 inches. However, their height is not a standard measurement, as fish are more commonly assessed by length. Overall, piranhas are relatively small fish compared to many other aquatic species.
