My Sinularia is necrosing...

[MJT82]

Hello all-

I have two colonies of green Sinularia in my tank. The colony on the left hand side is thriving, and growing nicely. The colony on the left side is shrinking and appears to be on a steady decline. The colony on the right side appears to have some tissue necrosis at the base, which appears to be the only difference I can see in the two colonies, and somewhat common from what I've read. My question is, should I go ahead and remove that colony from its attachment, cut it back to healthy tissue, and reattach it to new rock? I have also read that people will dose or dip their corals affected by necrosis in lugol's to address the potential bacterial infection. Can anyone shed some light on this? I really don't want to lose this coral!!

Of note, I recently (2 months ago) switched from T5 to Kessil LED's. The temp dropped in my tank by 2 degrees, but I have since corrected the temp to 79 degrees. Keep in mind, however, that there is a colony only 2' away that is thriving, and placed at the same level in the tank with very similar flow...

You can try cutting and reattaching to another rock. Sometimes this works. I bought a mushroom rock with a large piece of sinularia and it did the same thing, so out of desperation i cut it off and attached it to another rock. A couple months later the mother rock started growing another sinularia. The cuttings survived also. Good luck.

I would try and cut away the necrosis and then if you can dip the whole piece in a mild lugols solution.
I would do that before cutting it off the rock.
