I understand the difference between a realized and possible niche. I was thinking that a bottom feeding fish like a sucker would not compete with Bgill or LMB the way blue cats fit into ponds well with them. Those three animals fill diffrent niches, I wouldn't consider stocking blue gill and green sunfish, thats too close. Part of my question is if there a point to this at all? I see most of you think not, and you are probably right.
