Pectinia Help

[duke1215]

I purchased this coral last month. I believe it to be pectinia sp. I had it in the sand bed of my 90g under 2 150w 20k metal halides. I moved it to my 55g under 2 120w led fixtures when it started to brown on the tips and recede. It continues to receed and brown to this point. It was centered in the tank sandbed to give it the more difused light. Two days ago, I gave it an iodine dip to kill any bacteria and it continued to receed. Today, I moved it to a more light intense spot to see if that would help. My two questions are is it indeed a pectinia, and if so what type, and what can I do to save this beauty? All my other LPS are doing great.

That there is actually a platygra brain so lower light is required but also seeing the hair algae
in the pic you probably have alot of nutrients so your brain and your tank would benefit
from more water changes and maybe less feedings but overall lower the brain in the tank and reduce your nutrients.
Good luck with the recovery of your brain coral.

Now that you say platygra brain I see it. I was told pectinia by the lfs so o took their word for it.

It actually a Merulina ampliata. I saw some pics that look just like it. Seems to be a tough coral to keep.

Following along the lines of Merulina ampliata; it may be Hydnophora exesa. That would be my guess.
