Little flat red copepod, microscope image. Good or bad?

[Ohmegg]

Found these on the glass of my macro algae tank a near hydrozoas, I think they are hydroid eating copepods but just wanted to get a second opinion before I take some of the macro and rock out of this tank and put it in my reef tank. I assume since there are no corals in my macro tank then any "coral pests" would of starved out over 6 months...right?
