Looks like ostracods also called grass shrimp which dwell on algae but I dont want them in my tank. They are not long lived but reproduce regularly

I was asking about the creature in the center of the frame. Is that also an ostracod?

syllidae worm which sucks out juices of snails and other inverts. Get rid of it. Tweezers or tongs will be helpful with removal
