I have a YWG that I'd like to see if I can get to pair up with a shrimp. From what I've been able to read, they're most likely to pair up with a shrimp from the family Alpheus. But there are several different species, ie tiger, bulls eye, Randalli. Will one species work as well as another? Or do I need to do some more research. I do understand that just because I put a pistol shrimp in there it doesn't mean they're guaranteed to pair up. But it's worth a shot.
