I tried asking this question on the Tampa Bay Saltwater forum but got no responses so I'll try here. Four months ago I received at least four good sized pistol shrimp as hitchhikers with my TBS package. I'm trying to attach a photo from the TBS website. Might they pair with a goby? Unfortunately I can't find any info about what genus they are in. Anybody with knowledge or experience of this specific type of pistol? I would love to have the shrimp/goby relationship in my tank!
