Small creature ID please!!!

[chi]

I found these little dudes swimming around when I paused my powerhead. I had a tiger pistol shrimp in here before it got eaten by my elegance coral. There's also another paler blueish banded pistol shrimp that went missing. Are these shrimps or pods? They look like small shrimps even though the video isn't very clear. They're tiny and I lack a macro lens! Thanks gurus!
