Piranha is a name used for a large number of species in the subfamily Serrasalminae. The most popular and known species is Pygocentrus nattereri, also known as the Red Belly Piranha.
Red Belly Piranhas can live over 20 years and grow to about 18 inches/45 cm. Thus, you will need a large aquarium with a volume of at least 50 gallons (200 L) or even larger than that.
This species eats a lot, so you have to ensure the water is clean and that the filtration is good. Chancing water regularly is a must if you want to have healthy Piranhas.
The water has to be low in minerals, soft and its temperature should be about 75-80 degrees F/24-27 degrees C. Keep in mind to decorate the aquarium in such way that has hiding places, but also a large free swimming space. Young Red Belly Piranhas can be kept in aquarium with other species, while adults should be kept with other Piranhas of the same species.
This species can be feed flake food and pellets, but as they grow older, you will have to give them meaty food. Mature fish need low fat meet such as beef, fish pieces and live feeder fish. You have to feed them several times a day, while the young ones one time a day.
This species has a bad reputation for biting its owners, but this may happen only when they are underfeed and are starving. If you want to have healthy fish, these instructions are very important, so follow them and results will be great.
