Little white eggs and bristleworms(?)

[RW...]

Hi, ID please! Spotted a little beastie on my algae magnet last night, now there’s two.. largest is currently just over 2mm, reddish antenna, brownish spine, transparent legs. I think it’s a bristleworm, but my partner thinks it may be a baby shrimp. Also noticed little white eggs on the magnet and glass, and seen tiny little white beasties running about on the glass too.. Would like to know if this is good or bad news!
