Con Dao Archipelago, more unknown fish and ??

The second one is a little guy, about 2cm across. He moved in quick jerks across large spaces relative to his size.  Not like the dancing squiggly movements of the juvenile harlequin sweetlips but like fast darting movements with no specific direction. ( half my photos were of nothing  )

The third one...what is under the banded shrimp??

First pic try Epibulus insideater, Slingjaw Wrasse, Terminal Phase.

Second pic try Macropharyngodon negroensis, Black Wrasse, Juvenile.

Third pic I'm pretty sure that is a type of coral.  Do not know my corals at all.

Thanks Craig! 

Bang on on the wrasse!

Read the description of the black wrasse and looked at other pictures - thats definitely him!

I dont know corals either...need more books and more time underwater!

Happy New Year to you and thanks again!
