GoodPho~D;4297539; said:maybe wild piranha are but not if they were raised in a tank. People on here say they enjoy dim light but I think its how they were raised. Mine are actually afraid of the dark. I turn off the lights and they all go hide. Its only when I turn on the lights that they come out and swim around.
"a few years before they are 100% comfortable?" I really don't think so. I think its how much time you spend in front of the tank! my tank is in the living room with my kids running around in it all the time and my piranhas will swim right up to the glass and I can touch the glass with no fear coming from them. When I put my hands in the tank they barely swim away which sometimes scares me but as long as I know they are comfortable around me its fine just be careful. oh they are only about 5-6 inches. Beautiful fishes that will come out and show off if you take the time to know them.
Your paraphrasing is a lil off. He said "it CAN TAKE" years for them to be 100% comfortable. We all know they have different personalities
