looks like a pistol shrimp

 

[nietzsche]

btw, how hard was it to pair them?

 

[flricordia]

Not hard, just make sure their is a good size difference and the larger will turn female and color. Not gospel, but that is what seems to happen.

Putting title 'pistol shrimp' incase can be concidered for there also.
