Your LFS should carry copepods, and some even amphipods. Where are you located? Put your location in your profile, so it'll be easier for others to help you. I know Ali's Amazing Aquariums near me has live copepods. I don't usually see worms unless it is a freshwater shop. Or try OGreefs online, he's cooking some dense pods and has phyto as well. The next CFM is coming up in March, they usually have some vendors that bring pods/phyto.
