Yes, it's Helcogramma striata, the Striped Triplefin.

 

The top-down view makes it hard to see the dorsal fin split into three sections to recognize it as a triplefin.  But the colors are distinctive and this species is quite common in that area.

Yes, I've dived with Gerry Allen on the Nai'a as well, and these photos were shot on a Nai'a trip.  I'm trying to document the Fiji variants of the fish there, and am running into a few that are difficult to identify.

Someone on another site identified this as Stegastes fasciolatus, Pacific Gregory.

The skin flaps suggest Acreichthys tomentosus rather than Paramonacanthus.

In Topic: Some scientific names needed (Singapore)

The first is a featherduster worm, Sabellastarte sp.

The second is an oyster.

The third is a Paramonacanthus filefish.  I think that it is Shortsnout Filefish, Paramonacanthus curtorhynchos, though I am not certain.

Next is some sort of cnidarian, but I can’t tell from the photo.

Then the feeding tentacles of a sea cucumber, possibly a Neothyonidium species.

And finally, a coral or anemone, not one I recognize.
