Hey guys, one of the white cloud minnows in my shoal relentlessley chases the others around. I know it is the same one because it is the only one that is the golden variety, the rest are the normal coloration. Is this normal behavior? I would expect small squabbles to erupt now and again among the fish but this is the first shoal of schooling fish that I have owned which appears to have a single terrorizer. Should I isolate the individual fish for a period of time, or would that just leave a vacuum for another one to assume the role?
