Frogspwan coral help

[Kevin Haynes]

I have a frogspawn coral in a 25g tank with a kessil A150 ocean blue light and it was stung pretty bad by a torch coral to the point I was sure t would die. But now it's recovering and I can't figure out what this black/brown stuff is on the edge of the coral I thinks it's spreading around the edge of the frogspawn.

How contagious is it to other corals?

Is there a way I can get rid of brown jelly disease and how is it caused?

By any chance could it be red slime algae you think because it brushed straight off.
