It depends
h
the environment piranha's live in is usually in tropical rainforest waters. such as lakes ans rivers.
it is very hot
In the Amazon at wintertime, it snows. It also snow during summer; big blizzards, because it's WAY colder in summer than it is in Winter. I would advise burning down the Amazon rainforest, but it rains so much there, the fire would be put out. Oh well. I hope that information helped :) Love Alice
