Any thoughts?

I've not seen small sal****er shrimp offered like this before, so I suspect
that, as Tristan suggests, they're ghost shrimp. These are freshwater animals
and won't live long in salt water. They make fine food for any fish that's
interested (small lions, groupers, triggers, etc.), but don't dump a bunch of
them in the tank, expecting the fish to be able to eat for a few days. You can
keep a few alive for a while in a goldfish bowl, if you decide to make a habit
of this.
