help indentifying fungus/shrub ?
 

is it good , is it bad ...

lol

all I know is its growing fast any help would be great ..

Its in the back of m7 12g nana

The red macro algae? Fine I'm sure. I had some on my Koralia for the longest time.

Looks like it could be red hair algae? If it is, it's bad stuff.

If you look close to the tips of a strand of algae and it is claw shaped. Then it is Ceramium. It can grow very fast and take over coral and real estate. I'd remove if you have trouble containing it. It will remove nutrients from your tank upon harvest, But try to contain it on one rock.

Definitely a nuisance algae, it will manifest hard to reach places on corals and take over other real estate as well.

How should i go about getting rid of it ?

Anything that will eat it ?

thanks for the help thus far

Manual removal seems to work best, if you can take the rock out that's ideal if not, make sure to not let pieces float around and settle elsewhere(turn off pumps). But, you should have a herbivore in place to keep it from manifesting again, Emerald crabs are working for me.

alge
 

I tried the manual removal for a while. It seem to love being pruned and would grow back faster. My hermits did not seem to whant to eat it and the Tangs would not either. I tried a sea hare it was recomended to me( can't remember who) bottom line... I do not have to prune any more. The sea hare passes over any areas with this alge and... poof gone.
Hope this helps.

BAD. BAD. BAD.

My tank is over run with this s..tf!
Long spine urchins eat it (but only if there is nothing else to eat in the tank). My 4 urchins are grazing on the glass mainly.
Harvesting encourages growth (so it seems).
There are Turbo snails (not Mexican ones but Tonga) that eat it. Oceanic Corals gets them in.
I'll try a Sea Hare but the books only mention the urchins as being the only remedy.

My recommmendation: Throw out that rock.
Good Luck

That stuff is awful. I've had some in my tank here and there...a pain in the butt to eradicate. Pull out as much as you can, and make sure you catch all the little broken bits.
