T. Maxima mantle losing color?

As the title says. Not the best pics but you can see the clear area on left side.
Any idea of cause?

How long have you had this guy?

NanaReefer · Jun 17, 2016

Since March.

If nothing is shadowing the clam higher up it would likely be some kind of damage or infection that caused the bleaching. Could salt creep have fallen on it?

For better help a picture with white lights would definitely help people ID what the issue could be.

No shadowing, no salt creep, lots of new growth, quick reactions. Just the one faded spot.

Mat1018 · Jun 17, 2016

To me in the pictures it looks transparent. Is there anyway to get a better picture maybe from the top down in white light of the clam.

NanaReefer · Jun 17, 2016

Transparent aka bleaching right?

Mat1018 · Jun 17, 2016

I can't say it's bleaching or not. How long has it been like that. Have you noticed it spread? To me the clam has a good mantle extension. Colors can change slightly under different lighting conditions just like corals can.

Remind us what LED fixture you're using again?

I would not move the clam up at this point.

Radion XR30 G3. Clams directly under the light. Last par reading was 110+

Noticed the faded spot about a week ago. Can see it from my couch 5-6' away.

Definitely no plans of moving it.
