Help with Chromis ID

This guys are really tiny and purple, really purple. The pictures don't correctly capture the color.

those are yellow tail damsels.

EDIT: I think i see who your talking about. looks like a blue reef chromis, hard to tell from that pic.

They aren't blue chromis or green chromis, they are purple to a blue at the very tip of their nose.

The ones with the yellow tail are Chrysiptera parasema for 100% sure.
The ones with not yellow tail might be Chromis scotti, Chromis cyanea or Chrysiptera cyanea. But it's hard to tell from picture...
