I had just picked up two new piranha last friday. One 8"cariba and one 9" tern from Crazygn. Thanks Crazygn, those two are really killer, especially the cariba, He took over the whole tank just within an hour after I put him in the tank with my 12" piraya and 11" red belly. He even tried to gang up with rest of his fellow to kill my 7" black diamond which I had it inside that 125g tank with my piraya and red belly for over a month. Ofcause now I had seperate the black diamond.
