Alot of the piranha family is mostly shy and skittish, not at all like portrayed on tv, I can reach in the tank and try to grab them with no problems but when I had just 3 of them they had no problem eating a 12-13" tiger Oscar and now I have 8 idk even though they are skittish they are absolutely amasing fish and fun to watch, if anyone has any meat that’s going bad or dead/ live fish bring 'em on over if u wanna see some cool shit haha
