HELP-Why does my jack-o-lantern look like this?

[Lowefx]

These whit spots are appearing slowly and more relevant within the last month. What is this caused by?

What are your water parameters? Has there been any change to lighting or anything else?

 

[Lowefx]

No changes to light or location. It's been 3/4 of the way down on my 120g. And has not moved in almost a year. No3-16 po4-.08 sg-1.026, ca-425, alk-8.5 all has been stable.

That's interesting. Is this something they normally do? I've never seen mine do anything like this so I'm genuinely curious :)

 

[stylaster]

im not sure what causes an area to what im guessing is bleach out cause that's what it looks like. Removal to lower light fixed the issue. Mine actually gets the best metallic orange in low light. As for the feeding tentacles mine always has them out at night it looks like a hairy mess

 

[Lowefx]

Thanks everyone. I will try to lower into the tank. I hope that works.

How close is that favia in the second picture? Possibly some coral warfare going on.

+1, looks like it's dissolved tissue from some coral warfare.

Agree to all above.

 

[Lowefx]

Agree to all above.

It must have warfare on itself. All I see are it's own tentacles, and none at night.

The favia can throw up to 6" of sweepers at random times.

It's a Platygyra and it's been acting strange too. It won't take food and the ridges are starting to fade....

 

[DSC reef]

Platygyra, favia, favites, goniastrea, will throw long sweepers. It looks like dissolved tissue to me.

Ok, I shall separate them like 2 teenagers fighting!

 

[DSC reef]

Ha, ha! Time out for coral.

 

[Lowefx]

Let's see if this will help. I moved Platygyra to the bottom and under a rock to give it shade.

 

[Lowefx]

Still looks like this with no corals near by. Anyone else have any ideas???
