Yuma Ric in trouble?

[jsuprise]

I bought a yuma ric last week, pink and green real nice. A few days ago i notice that on one of the edges it is turning like a clear/white color. I thought something may be wrong with the lighting or flow, so i moved it to a little more shady spot with less flow. I have a 150 gal tank with 2x250 mh 10ks and 2 65w royal blue atinics. The yuma has always been on the bottom. Last night, i noticed that on the opposite side it is starting to look the same way.

Any ideas what this could be? What to check for?

I have several types of shrooms, but this is my first Ric. None of the other types show any signs of problems at all.


Phosphate and nitrates are 0
salinity is 1.024
calcium is a tiny bit high 490

I paid alot for this little fella and i really dont want him to die.

Thanks for the assistance

Rics can be really finicky. I have numerous Discos in my tank and they multiply and look great but I have lost 2 colonies of Rics-- they do fine for a few days then start to dissolve. My latest attempt is a single orange Ric polyp that is doing better than the others I've tried, but showing the same symptoms as yours. I've seen them completely bleach and then recover, so I'm just going to leave it be for now.
