Is this RTN/STN in chalice frag?

[KnightlyBuzz]

Is this tissue necrosis in this chalice frag? I got it about 10 days ago. If so, is it to late or should I try dipping in Coral Rx? If to late, is it a danger to other frags in this QT tank? I hate to do it, but I don’t want it to spread to other frags... throw it out?

Thanks in advance for the advice.

I did the coral Rx dip. See what happens. (crosses fingers)

It does not look like it but I could be wrong. You will see white skeleton if it is really RTN or STN. I would leave it alone and stop dipping to avoid stressing it more.

Ok, will do. Thanks! So far, he’s no better, but he’s not worse either.
