Just a type of copepod. Harmless and will eat detritus and be a tasty morsel for some fish. Very tasty. Totally normal reef inhabitant.

Actually thats an Amphipod.. (harmless/beneficial/very common)
Bookmark this link for future ID use.. Its got most of the common stuff and a simple Thumbs up/Thumbs down recommendation system..
A copepod is different..
