What's wrong with this GSP colony?

[flooddc]

I have this GSP colony for many months now (4 months). Its opened up and extended normally after I got it. Then about a week into, it stopped extending and looks like this (see photo) from then on. I also have a second colony GSP that was doing the same thing, so I moved into the refugium. It's been normal in the fuge so I left it there. I wonder anyone have any idea what wrong with it? possible lighting? (I moved it around to different part of the tank but seem to be the same).

Im having the same problem right now with my yellow polyps in my tank. All my other coral and zoas and everything is great but all my yellow polyp covered rocks have not opened in 2 weeks water prams are good and there all in diffrent locations and in diffrent lighting levels so it can be that. i dont get it

Thoose may be short polyp GSP. I have plenty of bright green regular GSP if you want any.

 

2nd post. Yellow Polyps are hard to care for and commonly sold as something easy. You have to feed them, they do not need light. I haven't seen many people successfully keep thoose long term.

A LFS guy once quoted to me: "if we know everything about reefing, then it wouldn't be called a hobby"

These were long green GSP, waving and everything when I got them monhts ago. Thanks for the generous offer. Just to far for me. Chuck

I think its the GFO reactor i added. I NEVER had a problem until i added this but i was having PO4 issues and the reactor fixed it. and all my other coral are loving me for it. I kept those YP for over a year and they fully extended and you couldnt even see the rock they were on. it swayed like a bush in the wind. now nothin dont know how to get them to open so what should i try??

look at them all the way to the right this was about 5-6 months ago now they just look horrible. i bought them as about twenty polyps

Sorry floodDC dont mean to take up your thread just seems like the same problem

Not a problem. It's appears to me that some thrives and some just don't. These (GSP, yellow polyps, xenia, kenya tree) are suppose to grow like "weed" for many people. My button polyps has the same problem as yours. got 5-6 polyps and triple in 1 month. Then all the suddenly shrunk. But now coming back around. Also, never had any luck with xenia. Tried many time unsuccessfully. But only one small frag survived in the sump.

I think you've eliminated water parameters as the culprit if they extend fully in the sump. That to me says it is either lighting or something in the DT that's bothering them.

You have a point there. Originally, I had a problem with the velvet damsel. He nipped at everything in the DT (killed may of my zoas colonies. however, I captured him a few weeks ago. Everything else seem happy, so the light shouldn't be a problem. Maybe I'll swap it with the other GSP in the sump as an experiment. BTW, when you are settled in Kentlands, maybe I can swing by to see your set up. Chuck

Sounds good to me. Still working out the lease details, but we should be there by the 15th.

[Mike Mann]

anybody else have any suggestions for these problems and if it is something i need to feed what should i try first marine snow because i do use that once a month.

A little update on the experiment on the GSP. I took another GSP colony from the sump (fully open up in sump) and place onto the DT. It's been a week now (including 2 days from the outage). only a small numbers of polyps from the colony open up. Most polyps remain closed. Oh well! I guessed I'll never able to grow GSP in my DT.

Consider yourself lucky. I had them overgrowing everything in my tank, and couldnt get rid of them.

[flooddc]

That's what i was saying previously. They grow like weed for many a people, but me! I like the grassy look in the tank.

[icecool2]

That means it is either related to flow or lighting. You can do some more experiments to determine which, but my guess is lighting.
