Montipura capricornis Red with problem

[Fleibel]

Dear,

I have a big Red Montipora Cap with several pups at various points in Aquarius .. for some time they began to become whitish and with loss of tissue at some points .. It is strange because pieces in different parts of the aquarium and with different heights in the reefs of different sizes are similar. The most stranger that I have Montiporas Purple, Green with Pink Tip, Orange and Green Electric who are perfect ..

My Aquarium has 11.000 litters

Anyone know what can be?

My green with purple rim plating monti had a few spots like that. Found that the flow was hitting it somewhat hard and to close to the surface. I fragged it, moved it lower and out of direct flow, now it's doing great. Not saying that's your problem but might give you a starting point.

Likely it's something to do with your water perameters or a pest. I wouldn't rule out lighting...can you share more about the tank please.

Are we talking about a flower pattern where the lower ones are getting blocked of light?

 

[Fleibel]

No,

With Light or without Light the problem is the same.
