Little grass carp turn into real big grass carp. And, as Cecil says, they like pellets a lot better than weeds. I wouldn't put them in again. This one came out of my pond several years ago.
We have a 44 acre lake fairly close by that is covered with weeds, and that the DNR estimates it has 1200 very large grass carp that they can't get rid of. Here is a little bit about the lake:
From the Charleston Gazzette, June 27, 2008. While carp are one of sport fishing's least sought-after species, they can grow to monstrous proportions. The state record grass carp, caught in Hardy County's Warden Lake in 2005, weighed nearly 72 pounds and was nearly 51 inches long.
Good luck,
Ken
