ID help please

Hi All,

Could anyone ID this.

there seems to be a couple star shaped things growing on the rock.

Here is another picture with more on the coral, they seem to be growing off the side?

Hi All

In the image below, the green plant has started growing very quickly in the past week. At this rate it would cover most of the rock in a few months. Is it ok to leave it?

I think that is Caulerpa

Looks like Caulerpa racemosa very fast growing and should be removed as it can quickly overtake your tank !

+1 Cheeks, it is a fantastic addition for a fuge if you have one but a total annoyance in the display

Thanks Glenn and Robert.

I will get rid of it right away. Not sure if my wife will want it the freeser though.

You are very welcome !

Hi,

Are there any issues with the green and red plants in the two images below?

 

[Shamus]

Not sure what the top one is, but the bottom one looks to me like sawtooth caulerpa. It's sometimes used as a macroalgae in refugiums, but can get out of control in the display tank (I had a caulerpa battle that seemed like it lasted forever!).

kill the green, cherish the red

Thanks Steve I took another type of caulerpa out a few weeks back so best to take this out soon.

The red plant has grown fast.

 

[Shamus]

Your welcome! That caulerpa can be a beast! Good luck!

Beautiful red macro! They're my weakness

Looks like it might be a type of Kallymenia with its spots. That or Halymenia. It's slick to the touch, isn't it?

Red = Halymenia sp

Green = Caulerpa serrulata
