Any idea what this is that's growing under one of my large mushrooms? I see two of whatever it is and one is at least an inch tall with multiple branches growing off a main trunk like a colt coral, but the trunk is tan and has green tips coming off... it is usually covered by the large mushroom that opens up over 3” every day but I seen this under it after a shrimp ran over the mushroom... I was able to touch it today with a pipette and it appears to be a soft coral of some kind...
