Many thanks to everyone for your opinions and information. After searching for data and studying I am going to go with the lake chubsucker. I really like what I see.
It does not compete for food with the bream or shellcrackers I have. Since I dont have or plan to have catfish it kinda takes their place (not totally) by helping to keep the place clean. They will not overpopulate like tshad and gshad will. They fit a nitche that I like in that their size can be anywhere from fingerling to 18.5in, however in my 3/4 ac pond its most likely to stay around 10-14in imop. They should be able to be sustainable even with my bass when I finally put them in. From what I read they deposit their eggs in the bass nest and look similar to bass when young and therefore have protection for a short time anyway. Lake Panasofkee, rodman damn, lake Kissessme (yes, I know the spelling is wrong) and a few lakes in the ocala area have noticed in the last 5 yrs that the chubsucker populations have grown by leaps and bounds. Guess what else has grown? The average bass size has growm by as much as 15% from my reading. I found a bait shop that has a contact that says they have a "few" and the guy is supposed to get them for me today. It would be nice to start with 25-50 individuals but I have time for them to grow. I dont intend to put predators in for a year or so. I also want more time for my lake grass and other plants to grow as well as my minnows, bream, and shellcrackers to populate. I think if I wait till their is enough plants and grass to provide good cover for my "bait fish" this will go well with my trees, rocks, and pvc to give an overall good habitat. Add the crawfish as soon as they are out of the mud and walah, good fish structure, bait fish, and eventually there will be some piggy piggy style fat belly bass to catch.
