What is the recommended placement and par for needles in haystack? See picture. It appears lighter in person. Just want to make sure I am not killing it with too much light. It is about halfway up with around 400+ par.

Also, please disregard rocks. Looks like the tank is new but I just added dry rock to an established tank.

This is a better picture with a 20k filter.

I had mine smack dab in the middle of my tank, maybe 300-350 par. It thrived before I crashed the system :(

That sucks about the crash. Did yours look like mine or a darker color? Hopefully mine is just getting acclimated. I had it fresh cut about 2 weeks ago. Had it in low light for a week then placed it in its location now a couple of days ago.
 
Sub 200 par it will have a greenish grey body and bright green tips, in your 400par it will be Ferrari red with bright green tips when it’s happy. The tricky thing with needles in a haystack is flow, they don’t like any direct flow, but a lot of indirect flow.
 
This species (I believe possibly Acropora carduus) should thrive in medium to high lighting. Loves good consistent flow as well.

Hope so. Bring on that Ferrari red!! That is where is currently is. Just out of direct flow and has good indirect flow.
