What type of algae is this (part III)

[henn]

Seems to be very popular topic here

Well, here are some pictures of an algae that grows on a Bali rock in my refugium. Recently I posted some of those pictures into another forum and got couple of guesses that it may be a Laurencia or Chondria sp.

Could you ID it? Thanks in advance!

Next two pictures are taken out of water in natural daylight.

Hi! :wavehand:

Let's proceed step by step :dance:

Acanthophora muscoides?
Some of the pics don't look quite right,
though thallus branching varies widely
from one specimen to the next,
depending mostly on water movement.
It's the reddish determinate branchlets
that hook me.

Thanks, horge :thumbsup:

It's certainly Acanthophora, let's hope not spicifera. I heard that tangs like it and put a bunch of it into main tank. It came easily off from the rock, so I guess it is a muscoides though. After couple of days I noticed that half of it was gone, although I didn't see any fish to eat it. Today my wife said that blue and yellow tangs and foxface were all together pulling off small branches and eating it like cows

OK, I have lot of still unidentified algaes on the same rock. If you do not mind here's the next one.

The same two weeks later.

More pictures for experts

#2
Beatiful red algae

#3
Could be Acetabularia, " mermaid's cup or wineglass"?

#4
Free floating "bird's nest". Maybe a sort of Chaetomorpha? Some "real" Chaetomorpha is seen on the bottom.

#5
? The tiny red dots on the branches are little flatworms, hope harmless ones
