Green star polyp

[Airphotog]

I have two green star colonies that are about 3x3" and one has not come out for a couple of days now. Anyone have any ideas? The one that is out is looking perfect.
By the way I got them at the same time from the same seller.

Are they in different lighting or flow requirements? GSP likes a decent amount of flow. It's not uncommon for GSP to take several days, even weeks, to open, after being moved.

A word of warning: Keep it away from any of your live rock. It can quickly spread, to any close by rocks, climbing your rock piles and taking over! Keeping it isolated from your aqua-scaping, will keep this from happening. Also, I'd advise to run carbon, continually. GSP is HIGHLY capable of chemically damaging other corals, through Aleopathy.

I have the same issue. I have two colonies that were split form one. Each is on opposite sides of the tank. One near the over flow on the right of my tank near the top of the tank that in the last several months just hasn't looked very good. Its getting medium to low flow and strong lighting. It grew very well there for 6+ months then just seem to stop and look irritated all the time for some unknown reason. The other part is on the left side of the tank in low flow and low light because its on the bottom of the tank that looks fine all the time. I don't understand why ether. GSP is suppose to like strong light but will do well in a wide range. I run 2 quarts of GAC changed every 3 weeks or so.

Hello,
That has not been my experience. It will retract and not grow well in 400+ PAR. IME it looks the best and grows the fastest in higher nutrient systems (5-10ppm nitrate) and readings of 100-200 PAR.
