Coral seems limp and lifeless

[webdeznr]

I have 4 corals in my tank, 2 are fine and 2 are struggling.
My "finger coral" seems to have shriveled right up and has a small yellow spot it what looks like the palm. I also have a mushroom coral which when i bought it would stand straight up. Now it leans to the side and the core looks shriveled up. But small pimple like bumps have started to show on the top.
I have purchased various bottles of conditioners and food and also new lighting but nothing seems to work, im worried dont want them to die.
Please help.
Thank you
Kelly

I used the dip sticks and all levels are safe....lighting is 2 T5's (if that makes sense) Apparently they are lights for corals.

Yes, post a pic please. And (I know it's tedious) post all of your water parameters and tank/lighting info.
Without knowing your system, I'm still going to venture that the conditioners and coral food are doing you more harm than good...

Ok I have added pics for you .... thank you for your help Im thinking placement is a problem.
But no matter what store I go to no one seems to know what advise to give.
Sigh

All of these are pretty adaptable to light (the more the better, to an extent - but they can handle less). I think the big issue here is flow. All of these octocorals will appreciate some nice water movement. Picture a tree in a nice, smooth breeze (not a windstorm or tornado!). I would move them up into the light a little more and definitely into some nice flow. They may freak out when and after you move them, but should come back out happier than ever after a few hours to a few days or so.

looks kinda like they are getting ready to molt *kinda LOL* They build up a wax layer and go limp and look lifeless at times to remove any debris and build up that might get on them. I would say that this is whats going on by looking at your photos. since you have a colt and a LT toadstool on either side of them that look like they are out fully.
Just a quick question and note. when you say you used the dipsticks. They are not the most accurate to test with. I would suggest getting a good quality test kit. also when you post issues its best to put actual numbers with the problem. This will allow a second, third, fourth set of eyes to take a look and see if there might be another issue.
t-5's are actually good lights. Do you know who are the makers of the bulbs and what K rating they are along with how old the bulbs are?
Welcome to the site.
ask any and all questions you might have.

to add to it also the better the water flow around these corals the easier it is for them to shed off the wax layers that build. Just add what MX#28 said.
