Greing Mark Ll Brazil has the highest biodiversity of fisn , the tambaqui , from amozonian can eat any nuts , thus vegetarian piranhas as obseved by Darwins may be possible , as well obseved by Mark.L. .When man become problems piranhas need to eat the aquatic grass and bacteria can make protein needed by piranhas , all has conected food web , wheer terra preta can play importnant role too
