3 kind of algae need ID please!

[Alex Kwong]

Hi,

I'm searching some good algae for refugium setup.
During this afternoon fishing trip. I located few kind of algae inside the fisherman home net (for keeping fish after catch).
Can anyone please help to identify the ID and also advise is it good for refugium?
Sorry, I'm using a cheap 95 bucks digicam, the pics is not so clear and the photo is took from the top view. So there is sunlight reflection...
I did not collect any of them. will wait for sump completed first.

Thanks!
Alex

Padina boryana?

Halimeda taenicola or Halimeda minima? look like minima

No idea what is this algae

The second & third pics is Halimeda copiosa. I seen it from
http://users.adelphia.net/~bcpatterson/Macro_Algaes.htm and http://www.livingreefimages.com/
The other two still searching for answer...

The last one looks like Caulerpa lentillifera or Caulerpa racemosa.

But color look so difference... could it be too close to the surface or too much fish inside the net...
