They also consume fallen fruits, seeds, algae, and seaweeds in the wild.

Though they have muscular jaws and sharp chiseled teeth perfect for catching prey, Piranhas generally like vegetation as much as they like meat.

IN CAPTIVE

Piranhas consume mainly fish pellets and flakes in captivity. You can also feed mealworms, Earthworms, krill, and some other feeder fishes to Piranhas in captivity.

You should choose fish food especially rich in animal components, to feed Piranhas. You can also provide them with thaw frozen food, fruits, and vegetables if they are omnivores or herbivores (which most of them are).

AS PET

As most aquarium-safe Piranhas are omnivore species, you can feed them with anything safe for fish. From fish meat, worms, and larvae to fruits and vegetables, they will eat anything natural, including dead and decayed plants and animals.

You can also feed any fish pellet or flake to Piranhas as a pet. The key is not to let them starve for long, as if they starve, they become aggressive and try to eat anything they will find.

And also, Red Belly Piranhas grows fast. They usually grow at a rate of 1 inch per month for about eight months. And then the growth rate slows down. So, it’s always better to buy a tank suitable for a fully grown-up Piranha.

Piranhas need a temperature between 75° and 80° F, a Ph level between 6.5 and 7.8, and alkalinity between 3° and 8° (50 ppm to 140 ppm).

If you keep your aquarium too warm, it may destroy their nervous system. If you keep your aquarium too cold, they will stop eating, lose equilibrium, lay on their side, and die.

Piranhas prefer to stay hidden, so you will need to keep plenty of hiding places such as plants, rocks, and other decorations in your aquarium. At least half of your tank should be covered for Piranhas to feel safe.

Piranhas are very messy, so you may need to keep more than one filter in your tank to filtrate water so that the water doesn’t get toxic.

You also need to change about 10 to 15 percent of water weekly to remove debris and other waste.

Piranhas naturally live inflowing rivers, so it’s essential to provide their natural habitat by making natural current inside your tank.
