piranhas rule
New member
i live in canada, Ontario and i had piranhas who unfortunatly died. my piranhas were well when i bought them and then when i took them home and put them in tap water they started to jump out or try to breathe oxygen but they seemed to be swimming fine. i left them overnight and woke up and i found 2 of them dead while the other 2 laying on their sides and they later died. could the tap water have killed them or what?
