My blastomussa frag is in QT at the moment. I can't identify what's going on with the one head that isn't opening. It has a few brown looking strings coming off of it. Any ideas? Red arrows are pointing at it.
Separately, can you confirm this is aiptasia (blue arrow)? I see only one polyp on this frag at the moment but would prefer to not introduce it into my DT. any suggestions on how to proceed?
I have a few other frags in QT with this one at the moment.
