Fish names, feeding, and two lone Xenia

My wife and son have named the two Pajama (PJ) Cardinalfish (Sphaeramia nematoptera): Polka, and Dot.

Fed them a dash of flake food.

Found two lone Xenia polyps:

• One on the rock that was below the algea, that was home to most of the Xenia prior to being moved - not sure how it got down past the algea. See it in the picture below between the the snail and hermit crab:

• One on the rock way out in front and much lower than the algea, that was home to most of the Xenia prior to being moved - not sure how it got down so low - I can't think of any way any peice of Xenia could have touched it.

An unidentified macro red algea:

The dislodged piece of trapped Xenia (from 11/16/05 Xenia Reoganization):

The transplated Xenia on the top rock:

Hitchhiker stripped Brittle/Serpent Star, perhaps 2" wide; and a Peanut Worm (Sipunculid) :

Colony of some "globe"-ish SPS (possibly Porites?), along with colony of polyps (Order Zoanthidea/Zoanthids):
