Those are kribensis, possibly ‘rainbow kribensis’ (I’ve just heard that name floating around and they look a little more rainbow-y than regular kribs).

They’re a bit like apistos - dwarf cichlids, mildly aggressive, shouldn’t really be kept with shrimp, although it’s possible. Maybe do some research into them. Good luck!
