I have YP, RES, SMB, and GSH my 1/4 acre pond. 3 dozen GSH were stocked in June of 2011 along with with 5-6 dozen FHM. The current 6" GSH are offspring of the original 3 dozen that I stocked.

The original 20 SMB are now 15-1/2" to 16-5/8" but I seldom catch them. I also stocked another 50 feed trained SMB in 2012 not knowing that my initial 20 SMB had pulled off a spawn. That first SMB spawn also had a lot of competition from GSH while they were young which led them to being somewhat lean which is still evident today.

New ponds are fun to watch the boom and bust cycles of things living in it.
