what to do with disturbed Green Star Polyp coral

[seavashr]

I bought Green Star Polyp and torch coral this weekend.

When I got home both were closed. The torch opened on the same day.
Maybe two polyps emerging from green star polyp but later closed, now after few days the green star coral is still closed.
Resources say "Star Polyps close or shrink when the Star Polyps get disturbed"

What should I do?

If your green stare polyp is in a area of higher flow or high levels of light, it likely won't open up for quite some time.

Edit, it looks like you have them about 1 inch away from some green mushrooms, but it is hard for me to tell how far. If they are close, like around one inch, I would certainly move the star polyps so they are at least 2 inches away.

Also, is the base of the coral really a light pink color, or is that just due to the picture? The base of the coral should be a dark purple color

Thanks Clif
Actually no "coral" was around it, that were my live rocks.

After about 3 weeks the Green Star Polyp coral is not opened up yet.
Since few days ago parts of the coral turned white (from the pink)!

Should I try to cut and separate the parts that is still pink? Whats should I do?


(The torch that was purchased at the same time is fine)


Thank you

How much light and flow is on it right now

[sheamurai]

Yes, +1 to Cliff. Green stars are generally very forgiving, it's likely either under too much flow, or too much light...well, actually, just too much difference from where it was before you bought it, to being in your tank now.

I don't recommend you do anything to separate the white from the pink. Just move the coral somewhere deeper and with less flow.

First: I actually moved it for a while to the bottom of my tank. It was there for a while and then started to turn white. As condition, I would say not too much light nor heavy flow.


Good News: I just checked it with extra care, about 8 small polyp are open, specially around the edges of the coral

BUT: I noticed VERY tiny white creatures that almost run on the surface of the coral, in the part which became white!

what could be? what should I do?

Hello everyone.

Now my star polyp coral is consist of two parts,
1-pink area with about dozen polyp opened, mostly at corner part (marked in blue)

2-white area, the skin in this zone is "rusted" and gentle blow of water pills it off, result in exposure of saturated purple color skin.

Polyps are started to gradually opening up in the pink zone. What do you guys recommend.

Should I keep the whole coral as is or try to cut and only keep the parts that started to open up


thank you
