Pistol Shrimp + Goby Add together

[Clowning_Around72]

Do I have to add the shrimp and goby at the same time or can they be added a different times?

I seem to have no trouble locating a variety of shrimp gobies.
Healthy pistol shrimp seem harder to find locally.

You can add them at different times.

Both my ywg + tiger and high fin + Randall’s pairs worked together when added separately.
I had more trouble with aurora goby + tiger (got a pair after a few months).
I would say it depends on species at least somewhat, but if you get the natural pairs then it should go well.
