Who wants to play "Name that Algae!"?

[Nirol]

I have several different kinds of Macro Algae that came with my TBS liverock. Here are a few different ones. Can you name them all?
Let's start with some red ones:

Here is another:

This one is more brown than red....

How about some green ones:

another green one...that's all I have for now...

 

[Nirol]

oops! Here is another red one (actually two kinds in this pic):

I believe one of types is Dictyota. Do yourself a favor and take care of it now. Once it gets a foothold it is extremely difficult to eliminate.

OK... thanks! Which one?

 

[sanderson]

It looks like the second and fifth pictures are Dictyota.

It looks like the second and fifth pictures are Dictyota.

The algae in the 2nd pic is hollow tubular, and stalky...the 5th pic shows a lacey tubular one and a flat flag like one...

Which would describe the problem one?

 

[sanderson]

Perhaps I am not seeing it correctly. Dictyota's branches are "y" shaped and thin.

[modemfox]

how about this one guys... i have no clue what it is

Looks like Red Ulva

 

[bluenassarius]

it's def. not ulva, the texture of the plant is hard unlike ulva

 

[sylphid]

if the texture of the plant is hard, maybe it's Sarcodia montagneana.
