I say to each his own......Im not going to go a give my fish some but....Its not doing the fish any real harm its just a cruel to keep them in a tank for there life rather that let them be in the wild if you ask me.......I mean really why make such a fuss about this...I dont think anyone is out there to cause there fish pain they are just trying to be diffrent and I say leave it be........ Sometimes there is just a little to much sensitivity in the world now a days
