Advice on struggling bubble coral?

[dmmitchell]

I purchased a bubble coral from AquaSD a couple of weeks ago. It showed up a bit rough, but has held on. I’ve included a photo here.

Any advice on how I might help it heal and regrow? Or is it a lost cause?

I think let it be. You can give it a dip if you want; maybe in an iodine based dip if it gets worse. You can add some aminos or some dissolved food too but I think it should be fine.
