Basic Information on Keeping a Piranha as a Pet

Overview:

Piranha are members of the Serrasalminae sub-family of Characins. The Characins is the group of fish, primarily from South America and Africa, that is best known as the Tetras. The Serrasalminae sub-family of Tetras contains the Piranha and their close cousin, the Pacu. These fish are from South America and have many similarities in both appearance and behavior.

Piranha are generally large fish, though not as large as the Pacu, smaller species reaching around four inches and larger species around twelve inches. These fish generally live for four to fifteen years, depending on species and care given (larger varieties tend to live longer). Piranhas have an undeserved bad reputation. They are unlikely to attack a large animal, like a human, unless they feel threatened or trapped, or are starving.

Equipment & Maintenance:

To keep a Piranha healthy, remember to provide them with plenty of clean, warm water. Your Piranha's temperature should be about 80掳 Fahrenheit, and ideally should remain between 76掳 and 83,掳 so you need a heater and a thermometer. Keeping your Piranha too warm for long periods of time will result in Oxygen deprivation, which can cause nerve damage, heart damage, and can seriously hamper the immune system. Keeping them too cool or exposing them to sudden chill can also hamper their immune system. An impaired immune system makes them more susceptible to many diseases, from easily treatable Ick to more difficult diseases such as dropsy or mouthrot.
