The reference to "pods" coming out at night seems to indicate to me you are referring to "amphipods".
Amphipods are sizeably different from copepods. However neither truly should be compared with artemia/brine shrimp since "pods" tend to cling to LR.LS.macro/glass, whereas artemia swim in the water column attempting to gobble up phytoplankton.
Generally speaking live brine shrimp you might purchase a LFS is not very nutritionous - though there is certainly protein in the adult shrimp. Breeding your own artemia creates fatty morsels (baby brine) that are more suitable for fish breeders. After multiple molts eventually artemia will become an adult - and at this stage it's quite loaded with protein.
But like all things feeding fish a diet exclusively of artemia is not wise. Also any you might add in a tank will either be eaten quickly or killed/sucked by your pumps.
So the end result of my ridiculously long post (sorry) is to say - pods would be unaffected by introduction of artemia, and feed artemia if you like as a treat for your fish once in a while. :spin2:
