Euphylia Bubble

[AWildZacR]

I have this small euphylia colony with 3 heads. Over the last 4 or 5 months it has developed this membrane looking bubble in the middle of the 3 heads. Has anyone seen this before? Good or bad? Thanks for the help!

Wow, that’s pretty crazy looking!

I know there different corals but my brain coral did the same thing. Got to be a 2-3 inch bubble then one day it look deflated and almost looked to be oozing down the side of the coral well anything that touched the deflated bubble now has new growth of brain coral on it I'd never seen anything like it

Hopefully it's getting ready to grow more!

I had this before on some of mine.
Nothing happened. they eventually went away. Had no idea what it was
