Please help, Coral disease?

[Evie123]

Hey everyone I have a question what this on my coral (my frogspawn). It is a brownish color compared to the normal greyish coral of the skeleton. I have attached some pictures in both black and white light. I read that these might be euphyllia eating flatworms? What is everyones opinion?

Can you circle the thing you're worried about?

It is this. It is a brownish substance and it is spreading really quick. I did not notice it earlier today and seems to be spreading quit quick. I also read that it might be brown jelly disease

All my other euphyllias are doing fine and do not exhibit any signs of stress. Therefore I sent this message. I hope there is anyone with more information about this. Maybe it is the flow? But that seems weird as it has been in that position and has been doing great in that area for more than 2 months

That's not what bjd looks like. It may be a sponge
