Ok, long story short, we had palys and mushrooms galore grow from LR we got years ago. Just started with some soft corals. I got this from Diver’s Den, LA. It’s a lavender hairy mushroom. I love moving them around and observing what they like. This rock had a lot of fleshy growth and I think a yellow sponge that survived my Bauer dip. I slowly moved it midway up and I think that fleshy growth it growing and secureing itself to the branching coral I stuck it on! Help very appreciated. Debra
