Anyone know what type of shrimp this is? Found it in an Aussie acro.

I second some type of pistol shrimp. How big is it?

Definitely looks like a pistol claw, but I've never seen one that was dual wielding...

Thanks for the replies the body is around 1cm (0.4") and claws are about the same size as the body. I have never seen a pistol shrimp with two pistol claws either.

I took the photo with a digital microscope https://www.jaycar.com.au/5mp-usb-2-0-digital-microscope-with-professional-stand/p/QC3199, which I think is just a clone of the celestron one https://www.celestron.com/products/handheld-digital-microscope-pro
I use it to look for pests on any coral I buy.

The very rare New Guinean Double Six-Gun Pistol Shrimp!

Dual wielding shrimp, so OP

Looks like a Coralliocaris graminea otherwise known as the machine gun coral shrimp

Appears to be a commensal shrimp known for hanging out in Acropora and other stony corals (makes sense). I suspect its similar in function to the acropora crabs we often see in the hobby. Neat find!
