New sessiles

[geweagle]

Hello all,

I have a couple of sessiles which have appeared in my living rock. One is like a fan with a bright green center. The other is a filamentous finger like polyp with looks like buds forming. I am new to this. Have no idea what they are and what light they like. Any ideas or point me in the right direction would be great. I have attached a photo

Thanks
