Got my LCS going with just 12, 3" fish, but at the time, I had a mess of curly pond weed in my YP/SMB pond for cover (mostly gone now). Based on the number of LCS that have washed out the exit tube, they are spawning and growing well. I also have RES and GSH in the pond. The growth on the SMB has been excellent and they too are spawning. Have not seen any RES, but everything else has multiplied. Moved some stranded LCS that came out the overflow tube to a new 1/2 acre pond that only has FHM in it, but plant growth in the new one is almost non-existent, and while I see schools of tiny fish, I don't see many larger fish (even FHM) in this new pond. Think the pond just needs some time.
