Here are 5 other facts about this misunderstood fish. These misunderstood fish can reach lengths of 8 inches long and weigh around 4 pounds. Red-bellied piranhas travel in groups for protection rather than to take down larger prey. Piranhas can make different vocalizations that sound like barking, grunting, croaking or the thudding of a drum. They use their swimbladder to make these sounds. Red-bellied piranha feed on whole small fish, insects and aquatic invertebrates and occasionally plant material and ripe fruit. At the Greater Cleveland Aquarium they eat an omnivorous diet, composed of a variety of items mixed in throughout the week. Things like prepared gel foods, pellets, occasional fresh fruit or veggies, krill and other shell fish and chopped up freshwater fish like minnows, smelt and trout, all make up a well-balanced diet. The red-bellied piranha is rarely seen in a frenzy unless they are extremely hungry and deprived. These fish get a vicious reputation in part because of some exaggerated claims made about them following one of Teddy Roosevelt's expeditions to the Amazon. His guides showed him starving piranhas taking down a large animal in a short period of time. While the widely circulated story from the President's trip might have made them legendary, it was a 1970s' horror movie that confirmed people's suspicions the piranha was a man-eating terror. You can take a closer look at the red-bellied piranha along with other curious creatures in the Tropical Forest Gallery at the Greater Cleveland Aquarium. Nature. It's a curious thing. – Tyler H.
