Two pistol shrimp in one tank?

[chautrung]

I just purchased a hi fin red banded goby and a red banded pistol shrimp along with some live rocks. When i got home i discovered that i actually got two pistol shrimp (one was a hitchhiker in the live rocks). Will the two pistols coexist?

Same species? It's possible, though I'm inclined to say not likely. It's also possible that they will kill your Goby.

How big is your tank? I've had two pistol shrimps (not at the same time). One was more active than the other but both took up approximately 65-75% of a Biocube 29, so if you have a big tank they may not run into each other.

Two pistols will ignore each other in a large enough tank from my experience.
You sure the other isn't a Mantis hitchhiker?

Same species (100% sure they're both red banded pistols); i tried to catch one to take back to the store but couldn't. The tank is a 5 gal pico.
