Small big like creature

[jcor1265]

Good evening! I just upgraded to a 125 gallon tank about a month ago and the last few days I’ve seen these little lightning fast black bug type things. Originally I stumbled across one on a pulsing Xenia rock and today have found them on my firework coral. I’m trying to find out if they are friendly or foe, sorry it’s not a defined picture but they are so so tiny. Thanks in advance!

Welcome to Reef2Reef!

Unfortunately, it's really tough to guess from the pics what they might be. Is there any chance you could get microscope pics of these for a better chance at ID'ing them?
