Very Odd Green Thing!

[OzKat]

Hi guys,

Can anyone enlighten me to what these are?
They started as one bright green thing growing off a Daisy Coral.
Now a couple of months later i have noticed there are 6 of them??

should i be getting these out of the tank ASAP?

Please Help.

Looks like some sort of macro algae, but to be honest I'm kinda stumped. Can you get a picture from a different angle? Sorry to be of so little help on this.

 

[OzKat]

They look like long tubes.
A different angle pic is not going to help.

 

[InsaneClownFish]

Yes it would actually. From the pic I can't see the tops clearly enough, nor can I see if they are calcifying on the bottom. Have you touched them? Are they soft and move with flow, or are they hard and fixed?

YEs its a type of algae, can't recall the name off hand.

yea it a type of calcium based marco Neomeris annulata usually doesn't last long in reef tank, growing in a small clump but if condition are right it spreads like zoa or gsp. I got two that popped up in my refug hope they spread. Definately reef safe nice find

Thanks "DJ" it certainly looks like that!

It seems to be a pest algae?
but they also say they are safe?
So if they are safe why would you remove them?

And to "InsaneClownFish" they are soft and move with the flow a kind of, and white at the bottom. They are not moving like the Goni or Daisy moves, "like flowing hair" but they are not solid like the Feather Dusters either.

I will try to take a pic from the top later today.

 

[InsaneClownFish]

Personally, I wouldn't remove it. It's most like a calcifying macro algae. However, in that pic if you look closely around the base of that algae there looks to be some bryopsis or hair algae around one of your whiskers- that I WOULD remove.

 

[OzKat]

Here's 2 more pics.

And yes...i do have some hair algae.
Any suggestions for ridding us of it would be appreciated.
Have tried less light, more magnesium, scrubbing (thats how i found the other polyps that we are discussing!), and less food.

 

[InsaneClownFish]

After seeing the new pics, I am a bit concerned they might be Caulerpa Racemosa stalks. If you see any small grape like buds form- remove it IMMEDIATELY and scrub the rock area with alk paste.

Take the Algae and incinerate it with a flamethrower to be certain...I'm not even kidding.

Considering your area, and the deep green hue, this is probably unlikely; but to be safe watch it carefully.

That site cant make up its mind. I am sure thats what you got and dont believe it will become a problem as to where or not you want it in your tank is personal preference. I just try to keep everything that i can in the thinking that diversity is the best way to success in this hobby and every little thing adds it own part.

 

[OzKat]

Thanks Guys!
I will keep any eye on it and see where it leads i think.

I'd hate to jump to conclusions and rip it out if it is a good thing.


I do have another query to post later today, with regards to another little growth in there.
This one i'm fairly sure will be a good thing.
But, as i'm no expert, i find it is always safer to check rather than assume.

Thanks again for all the great advice.

 

[OzKat]

Ok, i have this little macro algae (i think) that is trying to grow, but it seems it is quite yummy as it keeps getting eaten.

I hope you can see it, as trying to get a pic is quite hard, it's quite small at t he moment.
About 1 cm tall.
The "leaves" are about 1/2 cm across. It looks mushroom like but not squishy more like plant leaves.

Hope that make sense.

maybe some form of Padina hard to tell from the pic

 

[velvetelvis]

The first item looks like a species of calcerous macroalgae, Neomaris. It often sprouts out of live rock, sometimes months after the tank has been up and running. It can become invasive under the right conditions, but it's usually not a problem.

Can't really tell anything about the second one--it's hard to get clear pictures of such tiny stuff.

ETA: I see DJ in WV beat me to it. That's what I get for jumping ahead so I can be clever and put in my $.02. :lol:

 

[OzKat]

I can see why it looks like Pedina, but from what i have read of Pedina it doesnt have a stalk in the centre.
It grow directly from the rock.
and yes, my pic is not good. It's frustrating because i can see it quite good! Just not take a good shot of it! LOL
I will try again later, you never know.
But in the mean time... this one the "leaves" grow from a central stalk.

 

[ChknWing]

Its reef safe. I had some in my tank for a bit before it died. It is a calcifying algae. It is definitely nothing to be scared of

 

[OzKat]

I assume you are talking about the green stuff?

Thanks, i hate to remove anything that may be good for the tank.
But its hard sometimes to tell the difference!
LOL

Ozkat, I've got some of the same thing (Neomaris) from some Indonesian live rock. I'd echo DJ's and others' sentiments...don't worry about it. One of the coolest aspects of this hobby is to see all the diversity that reefs abound in. I'm just glad it hitchhiked on the rock and survived for me to see it!

I agree, we were always looking in the tank when all we had in there was live rock.
And the amazing things you would see!
LOL
2 years later and of the original rock we still have in there, some of the little critters and life is the original stuff!
It is an amazing hobby..... not the cheapest around.... but amazing none the less!
