I am new to reef tanks. I have a 36 inch 50 gallon tank with 24 inch power compact lighting and 50 pounds of live rock as well as 2 inches of live sand. Water tests normal. I just bought a green star polp coral. He came out a few hours after I got him butt hasnt come out for 3 straight days since then. Are their potential problems here.
green star polyp coral
- Thread starter bioscot
- Start date
i rearranged some rockwork a few months ago and my greenstars weren't to happy with their new sectioned off zone. for 3 or 4 days they wouldn't open up, now they are encrusting all over the place. i wouldn't sweat it they are pretty hearty provided you have acceptable water conditions. maybe you placed them to close to another stinging coral or your hermits are harassing them?
I wouldn't worry too much. They lasted through a 3-day 95 degree bleaching event in my tank, and didn't come out for two weeks. I have also scraped them off of powerheads, and then run the pump under hot water for 10 minutes while cleaning it- they grew back.
IME, the only thing that can kill GSPs are green mushrooms.

as an update I really think my gsp may be dying. Some of the purple pieces of the rock seem to be chiping off. I heard this was a bad sign. Is this true. If my calcium is good, and i have no unusual nitrates what could be causing this. Is this somtimes as unavoidable as loosing a new fish or do I need to dig deeper...
Corals are amazingly resiliant - hence it's quite common for one to take 6-8 months to die. If a coral crashes upon introduction into a tank within days then there is likely something wrong.
However I do not think anything is wrong with this coral offhand however we need to know more. What other corals are in the tank, what kind of water flow is the coral being subjected to, what is the temp, salinity and alkalinity levels of the tank?
FWIW Calcium levels will have almost no affect on this coral as it uptakes little if any.

When I was moving the tank, my gsp goes a week without opening up. Have you moved it recently, it doesn't like to be moved, touched and out of water for a brief period. I even take some pieces that are peeling off, cut it and place elsewhere. The broken pieces always grow back.
Honestly, I still wouldn't worry too much, Just leave it where it is, give it a good water flow, and usually it will grow back.

my ph is at 8.2, the temperature is 76 and I will have to check the salinity but it doesnt change much as i do periodic water changes with ocean water from the fish store and keep up with evaperation. I have two powerheads, 1 was pointed almost directly at the gsp. The corral is almost 2/3 up the tank. I am new to corals and purchased this and a mushroom coral last weekend. These are the only 2 so far. If he is not in trouble what might the interpretation be for several of the purple pieces of the rock starting to chip off. Not to mention he hasnt come out since I bought him.
When I first got my GSP's they were closed for almost a WEEK!! Then, finally, one or two opened..then three , four, 10, 20.....
During that initial week, the purple started flaking off, and it looked dead also.
Now, I just added 2x96W PC's and WOW!!! there are already 5 "Baby" GSP's and new growth of the purple stuff around it.
I have mine at half depth in the corner opposite the of powerhead, with its current right over them.
I wouldn't worry about it for a couple more weeks.. I thought mine was dead also..
It is a possiblility that its dead, but I really doubt it - those are hard to kill if I remember correctly.
Got any pictures?

will Tom I now look stupid..you were right my salinity is at 1.026. The question is, can i still save the gsp and how much water should be taken out and replaced with fresh water. Also what is the most efficiant way to treat my fresh water.
thanks again for your help!!!!!
thanks again for your help!!!!!
ummm don't touch a thing, the salinity is fine
I was expecting it to either be 1.023 or lower or 1.030 or higher.
1.026 is about right - leave things be.
For tap water I would run it through at a minimum a DI cartridge like Aquarium Pharmaceuticals Tap Water Purifier. Otherwise I would suggest you purchase an RO/DI unit - many of these such as the Reef Pures are rather economical these days. Though TWP's are about $30-40 online.

I agree, unless you see the tissues disintegrating into powder, just leave your gsp be, it will come back one day!
When you do water change, how much and how often you do it? You never treat your tap water? FWIW, there could be anything in the tap source.

I agree with the other that these guys are practically indestructable.
My example comes when we had lost power for a couple of days during an ice storm and the tank temp dropped to 42 degrees.
Well the mushrooms perked up fairly quickly but the GSP stayed closed for about 3 weeks. I was ready to pull them out and toss them but my wife convinced me to leave them in. About a week later I saw 2 polyps emerge, then a few days later more and more until the coral was back to normal.
I know when I have moved mine within the tank it takes them a about a week to all expand to their previous condition.
Give it time and I think you will start to see these guys emerge.

I do water changes with seawater purchased from the fish store. I do have a ro system in the house and i use it for evaporation but it wouldnt have been enough if any major change in salinity needed to be made..
You guys are starting to make me believe this thing is going to come back to life!!!!
