At year one and two (last spring), each, I've tossed in six pounds of Louisiana Red crawdads, in a tenth acre for a bass and catfish treat. My two water lilies planted in containers (plastic lined pond) at day 1, miniature varieties from Home Depot or Lowes, still dormant when adding crawdads, did great regardless. I still see one occasionally that crawls into a fish trap or my fish holding box.
