Introduction
Piranhas are very interesting fish, people say that they are very aggressive but they can be very loyal too; I have 7 of them and they follow me back and forth.

Feeding
Piranhas are omnivores and they eat a lot!
Don't feed them live food only; it can become quite expensive, try to feed them pellets and dry food mostly and feed them raw meat and shrimp occasionally.
Freeze the live food before feeding to kill germs.
Lighting
In nature they live in dirty water where lights can't reach that clearly so they are a little afraid of lights; so put enough hiding places and driftwoods (I found this info from fishlore member [Trpimp 147] and my piranhas are a little afraid of lights too.
Filtration
They get very messy during feeding time so u will need extra filtration and frequent tank maintenance.
Size
They grow up to 12" but our local versions grow up to only 3"!
The problem is that they can grow up to 14 inches if it is a red piranha [Wilhem Joshua Tan].
Temperature requirements
Temperature approx. 22-27 degree C. (71 F - 80 F)
Tank mates
Don't keep them with other species of fish; you can keep large plecos with baby piranhas.
Tank volume
It's better to keep them in a school of 4. They need at least a 30 gallon tank but you can keep babies in a 10g.
Aggression to their human
Baby piranha will bite you...piranha are braver when they are younger. Not that I recommend anyone putting their hand in the tank. You have to get to know individual fish to see how aggressive each one is. We had a 12" female red belly, Bessie. I put my hand in her tank just once...she had gentle eyes...Now we had wild caught caribe (sp?) piranha...those thing were nasty. My hand never went in a tank with those creepy fish. [Allie]
