What should I do with this unhappy Ricordea?

[Just John]

This Ricordea has been receding on one side a little more every day and loosing color in that area. The color difference is greater than it looks in the photo. Should I cut it in two, leave it, dip it in iodine, or something else?
Have you ever had this issue @Kristopher Conlin?

IMO the area circled is getting too much light or flow and is irritated. Cure the irritation and it'll rebound

It's in the same spot it has been in for months. Maybe I should move it to a calmer are away from everything else and see what happens.

Have you checked under it? Possibly a hidden aiptasia, vermetid snail, etc.

Also. If this was a "piece chart" of my Life...the circled area would represent my marriage....... irritated

No, nothing there that I can see.

Is there another coral nearby that's stinging it? Is that part of the ricordea not supported by rock or rubble underneath?

Yeah who knows I have certain coral that recede now and then but they always recover sometimes it is caused by a crab or shrimp that crawl over them.

 

[Pistondog]

Leave it.

Looks like you have cyano.

No, just sitting next to the other Ricordea as usual.

Actually it's green algae. It looks dark under the blue lights. The Turbo snails are too big to fit into that area, so there's always some there.

If it's not happy, it can move. Mine have when a bta invaded space.
