How much light are you pouring down on them. I see one in the back ground doing the umbrella. All those pictured are pretty much varieties of Actinodiscus, Discosoma sp. They don't take MH very well especially alot of wattage. You don't mention much of anything parameter wise so judging from the brightness of the photo's, the good coralline algae growth, and their condition I'd make a guess that your burning them up with the light. If thats the case you need to find them some shade, overhangs, places where they can rest and be slowly acclimated to your light intensity by moving them out and up over many weeks to where you want them.

To do a better job we'd need to know when you got them/how long you've had them. What kind of light and chemistry you currently have. Any observable conditions by you that might adversely affect their health, i.e. something picking on them, temperature spike, new light bulbs replacing older or recently burned out ones. Throw us some crumbs =)

They are new for me, from another tank
The lighting was very close between tanks
250watt 10k X2
80watt T5 actinic

The top pic was left out of water for close to an hour.
It was on some rock that I missed

The second pic, those are near the bottom with no shade
The 3rd is up high with no shade (this one looks good)

Maybe I should shade them all?

Water parameters are all good.
I use RODI water

Those two 250watt 10k's are pretty scary for Discosoma. I would shade them a bit. Any that are having issues give them some shade and then slowly move them over time where you want them. Mushrooms are pretty hardy and once they get used to your setup they should do well where ever you want them except up near the top of your tank under those lights =) They may color shift a bit. Especially if you move them more towards the light than they were situated in the tank prior or if there is a spectrum change. Also if they cannot get used to a position due to light or current, they may leap off the rock and move elsewhere in the breeze. It's possible you may have to go hunting for some.

That really is alot of light for that type of coral. Bottom of the tank. Shady overhangs. Small caves. Move them and maybe lessen the length of day you have the lights on for a little bit. Shorten the photo period. Don't put them in the complete dark though. Just out of the direct light and in a lower current area. Even leaving the lights off for one day or just turning off the MH for a day might give them the rest they need to recover.

Some of mine looked like the ones in the 2nd pic. I moved because I though that they where getting too much current. They opened up well after I moved them.

I think I'm having the same problem. I have a fragment that started with 2 discosomas 3 years ago (1 red 1 purple), then they started to multiply. I moved to my new tank in january this year, with new lights and a MH.

First the seemed soft and smooth, now the look like burned and rugged.

Is there any way to help them besides moving them to a place with less light?

Mine seem to curl up with the lights out.
I was concerned with pic #1
The seems enlarged to me.

I notice that they shrink almost in half when the lights are out.
1/2 dollar size down to a quarter

Is this normal?

They all look good with the lights out. Except the one with the big mouth. It sways with the flow, not stuck to the rock very well
