Amphipod?

Interesting. I don't have a sense of scale/size. To me it looks like a mayfly larvae but they shouldn't be in saltwater, much less in a tank.

Well my tank is right by the sliding door leading to my deck so it could be an outside bug that died in the tank lol that’s why I posted it here.. just wanna make sure if it is a hitchhiker it’s not a bad one

Yes, looks like an outside bug, not an amphipod. Amphipods are laterally compressed, this is just the opposite.

I already got rid of him but I’d say the length of the body was almost a 1/2”

Also amphipods are great to have, I've added them to my tank several times, but so far they haven't really gotten themselves established like the copepods have.
