What is this?

[kingtoad]

I have no idea what this is. I was looking at an ID website and I think the closest thing I saw was mushrooms... but they had an unusual shape, unlike this one. What is this?

It opens up in the daytime

Irrelevant to the topic, but how do I feed this? Also, how do I feed my coral?

 

[HaKs310]

Green Star Polyps.
No "feeding" needed.

 

[peregrinus]

green start polyps. they will grow fast and cover everything.. the filter and use light to grow.

 

[kingtoad]

Thank you.

It's not green star polyps, with the color (the encrusting part looks like it, though). I was thinking it looked a little like pipe organ:

...but I changed my mind because the encrusting part just doesn't look calcareous enough:

I think you might just have a variation on GSP, of another color. I think I have heard people call it clove or daisy polyps.

 

[kingtoad]

Thanks for the info!

 

[HaKs310]

Yeah, star polyps, also called daisy polyps.

Clove polyps is used to refer to coral species in the Clavularia genus.

Thanks Haks. I have seen GSP classified as Clavularia viridins also, though (I have them on my own site as Pachyclavularia). Would you happen to know if this is because of old classification schemes?

 

[HaKs310]

Both Clavularia and Pachyclavularia have similar growth forms, so they are mistakenly switched around. Pachyclavularia violacea, is the correct name.

Hello again.

Do these need waterflow to live?

 

[HaKs310]

Yes, they will need moderate flow to keep any algae from growing on the mat. Which, will inhibit the polyps from opening if it does take a foothold.

 

[kingtoad]

Thank you.

 

[avshockey311]

Also, about the flow....it is best that they get a "whip" style flow rather than a constant flow to them.

If you have actinic lights then if you put them on they will turn green. I bought a small rock a couple of weeks ago coverd in them and if my actinics arent on then their brown.

this is one of my favorite corals. you can rip chunks of it off the rock and superglue them to other rocks - they grow extremely fast. I've seen some people glue them to the glass even

Ouch!


Can I do that?

 

[HaKs310]

Yes. You can use a razor blade or scissors to cut off part of the mat. Then glue it onto the surface you want.

make sure u have good water circulation over star polyps
