I must really be ignorant. I don't even know what a Rich Rod is, cept' for that awakening time in my chair. I thought it was an Infomercial and changed the channel to Gunsmoke.
Former WVU football coach who turned traitorous and left for Michigan's head coaching job. He was forced to pay his full $4million penalty clause, so that hints at the cloud of suspicion under which he left. (Sorry Bob or others who may have been put off by my injection of football chat here!)
So, turning it back to HSB, what would be the reasoning that a state would outlaw them? Reading the posts here and in other threads, if they are either incapable of reproducing, or if the conditions for reproduction are insufficient, it doesn't seem like they pose an overpopulation risk. As well, I have not read anything that seems to suggest that they would become a true invasive species in the sense that I have come to appreciate that term here. I'm going to have to see if they are legal here in WV as I'd be very interested in adding them to my mix when I renovate my big pond one day.
