did my green moon coral kill my pink yuma?

[lastlight]

Yuma has never been 100% in my system but it was doing not too bad. The moon coral was on a shelf above it and i think my elusive large crab knocked it over. I came home and the moon was upside down on top of the yuma. The yuma was surrounded with a white fuzzy tissue like mould. I tossed it out.

Is this a case of the moon chemically killing the yuma? Will the moon be ok? In the area where it contacted the yuma it is slightly pink but otherwise looks great.

Thanks!

It was not chemical, a moon coral (favia??) is aggressive.

The yuma got stung. It might recover.
