Yasha goby and pair of randall's pistols


New member
Last week I added a Yasha goby with a pair of candy stripe (randall's ) pistol shrimp to my 36 gallon bow front mixed reef.

I am wondering if there is any way to tell what gender the goby is and if it would be possible to introduce a mate for the goby as well. It's cool enough seeing a pair of the pistols, would love to have all 4 sharing a den.
