Trouble with my Acan.

[AlohaReef]

Hey Reefers! I've had this acan for a few weeks and noticed that a few of the heads seem to have shrunk and turned a fluorescent green. When I initially set these on the frag rack I think I set them too close to some acros & it got stung. Does that seem like what is happening, & should the heads recover, or do I need to remove them?

Thanks all!

Low light low flow. Do you feed it?

It's in the bottom corner of the tank, only a few of the heads are turned green. I broadcast feed the tank mysis but never have fed any corals directly.
