Honestly why do you care.
Because that is why I'm involved with piranas all my life. It is not a game to me, it is my life's blood, my passion. Giving out information based on science is also a passion because so much erroneous information has been published about piranas. I have met the tiger (Fish and Wildlife) and it is because of these people and others like them that prohibit pirana possession because of bad information. When I read about how hobbyists perceive their fish in the aquario as a killing machine, do you have any idea how this forms opinions in the unknowing minds or in situations where this board is being visited by DNR people to see if they can create new laws which can be cited by hobbyist information? That is a fine line, one that cannot be ignored, not by me anyway.
People can choose to believe what they want, that is their right. However, I would not be of any value if all I did was sit back and not offer what I know to be supported by evidence. But if you would prefer I do that instead, I can accommodate you and this forum will simply revert to the same nonsense posts that have plagued other pirana message boards.
Arguments continue to surface and misunderstanding too because some hobbyists use their home aquarium as tools to say certain things happen there. I have no problem with that so long as it is generalized. However, I also find when reading that certain statements are made which are not generalized and are written to make it appear that is how piranas normally behave in nature. That is where I step in to pull in the reins and separate what you see in home aquario and what is seen in nature.
Mike (Xenon) asked for my input here from a scientific level. If this is to much for some of you, then perhaps I can step back and allow the discussion to go unchecked with bogus claims and unsupported evidence based on 2 or 3 little piranas in the home tank.
And before the wrong idea is taken, I'm not angered by this, I'm simply retired and don't need the headaches LOL.
