Please help, I am attaching some pictures, 2 are from a week ago and 2 are from today, something has happend to my Green starburst and I dont know what it is. PH-8.4 SG-1.025, calcium is just over 400, I supplement with Tech-I once a week. Ammonia-0ppm, nitrites-0ppm, nitrates-20ppm. PC lighting and plenty of flow. This coral is only a week old, I have not noticed any problems until yesterday, when I woke up and it looked like crap. This is the only coral in the tank, other than that I have calupera grass and some fish. thanks-Justin

Hi i have had a similar problem with starburst colonies, a week or so after i had purchased them they were all out and in good form.

Then i woke up and found that they had all retracted within their casings, this went on for about a week or so and thought they were dead, then suddenly they all came out again.

Hope this helps but try stick it out and see what happens, oh and my nitrates might be slightly higher than yours.

that is so strange. I wonder if this is a normal thing with this type of coral? This is my first coral and I was worried that I did something wrong. Well I hope it comes back because it sure is nice to look at. Thanks for the comments.
 
What type of lighting do you have and how long are the lights on? Perhaps you have them too deep for their preference. I too recently purchased a "rainbow rock" that also has them and they closed up once I put them into my system for over a week. Found out my water temp was just a bit too high for them--dropped the temp to around 76 and put a small current across them and VIOLA they are back!! Looking at the pix it appears they are receding not merely retracted so you may have more of an issue--do you have any marauding critters in the system?
 
lighting is a PC lunar aqualight(coralife) the coral is at the bottom of a standard 46 bowfront in direct flow. The guy at the LFS told me the coral would sustain anywhere in the tank as long as it was in good flow. The lights cycle for about 10 hours, lunar light is always on. All reef safe characters in the tank, only fish that gets near it is a scooter blenny and all he wants to do is lay on it, not eating it. I was out of town for christmas and the coral looks a little better when I came back yesterday a few more of the polyps are open. I see that a lot of people on this forum add supplements besides the standard calcium and trace elements, I see things like coralvite and plankton, I thought that corals were photosynthetic and convert the light into food, should I be supplementing with some kind of food??
 
I've got the same set up! I'm running an Eco-system 40 filtration system and a Remora skimmer, with an 802, and Rio 200 (?) powerheads. I recently added a Pet-zoo 228 sweeping powerhead to give it the wave affect. I've got my polyps about 8" deep and they are just beginning to grow like gangbusters in size. I would recommend putting yours someplace where the Scooter doesn't sit on them--that will keep them retracted and could concievably cause them to starve. You should be feeding them Phytoplankton too for the best results. Just my 2 cents.
 
Okay I don't believe you can kill these......I have tried....I have them in both my 75 and my 20. In my 20 they are under pc lights and have spread over everthing....including climbing up the stalk of a sinularia and smothering a toadstool......the only thing that is keeping them in check right now are some mushrooms and a frogspawn that comes in contact with a portion. Mine spend part of the day retracted just like that and then come out in full force for hours then retreat later when lights are out, not always but sometimes......if these are stressed.....sure is news to them. I have scraped them back and put the scraped pieces on rubble with rubber bands and propogated them this way.......yours looks fine. Just watch it for a few days/weeks and make sure it is spreading. You may curse it later
 
Mine did the same thing and I noticed a very small aptasia on them. I pulled them out, killed the aptasia with Stop Aptasia and now they're back to normal.

Don't mean to go off topic but your nitrates are too high. GSP aren't super sensitive and I've seen them living in some filthy water so I don't think that's your problem but you should find out why your nitrates are so high. FWIW my GSP and yellow polyps close up for a day or two on a regular basis. I think part of it is that some of my fish will feed on the pods that live amongst the casings.
