I have owned other large fish ans cichlds in the past but never piranha. I saw 5, 4 to 6 inch piranha at my LFS today. Very nice looking fish. The guy said He sell me all 5 for 60 dollors. But he showed me a alge scrapper that had a U shaped chunk taken out of it. My question is Do I run a good chance to getting bit while cleaning and arranging a tank with piranha in it and if so How much damage can they do to me. I really like the looks and color of them but don't want to loose body parts to a fish.
