TopH2O :

Theo has GS and has some reservation in stocking them. I don't have them but think they are a good option. They have a med. doubbling time for population 1.4-4 yrs. Here is repod. data.

Reproductive Habits:
� Mature at age 1-3
� Spawning occurs April to October in water at 15-21�C
� Eggs are adhesive and laid over vegetation, gravel, and nests of other fish
� Fecundity is 200,000 eggs per female

They will eat both BG and LMB and other eggs and anything else they can fit in a small mouth. This should help keep the LMB rect. down (good) and in one study a cousin shiner was not near the biggest predator of BG eggs ,it was 3-4in. BG which by far ate the most BG eggs. GS do get big at 12in. They spawn often and eat plants (FA and zooplk.) as well as pellets.
