Sunny D's Need Help

[NeuroticAquatics]

I got this colony of Sunny D's about six weeks ago. They went from looking great (first pic) to not opening up all the way (second pic). Same location, same flow, pretty much same everything. It's been a couple of weeks of them not looking so great. All other zoas and corals look the same as they always have. Any suggestions?

They look to be stretching in the second image, so possibly more light, but don't go crazy, move them higher slowly over time. They don't look bad, they just don't look very happy. I have a rock with about 40 polyps on it in high light and flow.

Zoa's take time to adjust to a new tank. Every time you move them they will take time to adjust (like months) before the start to grow. I have sunny's D's on my sandbed and on my highest rock. The both grow at about the same rate. They should adjust.

What lights are you using? They look burned

It is just an eBay knockoff with blue/white LEDs. I did realize that the Blues were very dim this morning, so I switched over another one.

They seem to look a little better. Maybe not enough light?

I was always told if they're stretching then they're not getting enough light?

They need more light, but they first will need to heal from being burned. How long were they in the tank before they started to tuck their skirts and lose color? That's a sign of too intense light too fast. The long stalks and big polyps are because they are palys, but those stalks are too long as they are actually reaching for light. Hard to explain. Move them lower and let them heal and then slowly, very very slowly move them higher.

I will move them down. They were up about mid-tank for about a month before they took a turn.
