When you are culling your own fish you bred it's fine, Never use feeders from the LSF. I raise a lot of fish, if a fry doesn't look right, i.e. not good enough to sell it gets fed to something, When I import Crenicichla or Cichla, wild predatory fish won't eat prepared foods right away, I usually have some baby Amphilophus that can get them eating until I can switch the over. I prefer to feed everything pellets. Ken
