Invertebrate pest?

Hi, I was doing maintenance in my tank and i noticed this little fellow lurking under a rock. It probably came with my live rock considering that I haven't introduced any corals yet. Should I be worried about it? Thanks!

Looks like an amphipod and is harmless. I'm not 100% sure tho.

Yes some species of pod and free fish food. Good sign of tank diversity also
