Most of the “bugs” look like Copepods while the large one in the first picture looks like a Munnid isopod. Both are “pods,” will rapidly reproduce, serve as live food for larger organisms, and graze on algae and detritus to some extent. Also, Munnid isopods have straight backs while Amphipods have curved backs.
