Any changes in lighting, water quality, inhabitants? Could be any number of different things. Cant make a guess on the pics.

ammonia- 0
nitrite-0

turbo snails
conch snail
brittle star
hermit crabs
corals-

any idea what can be going on? The rest of the star colony is open spreading and doing great, as are the rest of my tank inhabitants. Your help is greatly appreciated. i have not noticed anything preying on the stars. :notsure:

lighting is the same all though i did turn the lights off a few hours earlier than usual the other day. would this cause something like this to go on for a few days? by the way i have 265 watts of pc lighting over a 55.

They look like a group of stars that I have....not GSP but a brown with a green tint. Mine looked like they were wilting away once, but they bounced back. I think it lasted a couple of days. Could be that one of the inverts was stomping on it also. I never new what caused mine to act like that.

When you changed the water is your ph and alk good? It looked like the coraline on the rock nearby was whiter than before which is a sign of ph/alk swing. Just a thought, Carrie

carrie,
ph- 8.2
alk-10.5
i think the white stuff is just sand. i do have some white coraline though. i just thought it was from the rock hitting oxygen a month ago.

Looks like a touch of cyanobacteria- get a little more water flow on that part and im sure they will be fine- The colony still looks great BTW- A water change couldnt hurt either

What is your watts/gallon and what sort of lights are you running? How old are the bulbs? Are you adding iodine supplement to the tank?
My LFS has a nano reef set up and they have GSP in it. They have lost the green coloration to the. I believe this is due to being in low light situation. They only have 2.6 watts/gallon. Better to have 4 watts/gallon. Their GSP are surviving, but lack the proper color.
I have a 55gal reef as well. I have 8 watts/gallon. GPS are doing great. I have them isolated so they can grow much on other rocks, but still be able to grow up on to the glass. Anyhow, I hope your's improve.
There is also another color similar to GPS. It is commonly called pink star polyps or brown star polyps. However, they are encrusting Gorgonians. The grow on a mat just like GSP.
However, your's looks as if they lost their zoozanthelle.

i have 265 watts of pc lighting over a 55 gallon tank, which is about 4 watts per gallon. i dont think these are actually green star polyps. they look sort of pinkish with a green tint. the rest of the colony is spreading and doing great. it is just that one area that looks like that.

My green star polyps like medium light and medium to light flow. I have them in a semi protected area. Maybe some dirt or sand got on them in that area, try a turkey baster and lightly wash off the area, couldnt hurt to wash off with cyclopeeze (the frozen bar kind)everything in my tank seems to like the cyclopeeze esp. the candy corals. Check your temperature also, I had to learn the hard way about too high heat trust me!! Carrie

the purple tubes that the polyps are coming out of are turning white in that are that open? is that area dead? should i remove those peices from the rock and let the colony spread over there?

it looks like a cyano overgrowth on unhealthy tissue- brush it gently with a soft toothbrush and move it to an area with a bit more water flow- it is by no means lost.

far from it. It looks like they are actually more colorful since they were first purchased. lighting isnt the issue for this case-
also eric they are GSP- there are many different color forms for these type of polyps- HTH
