Hello, I am new to this forum. I purchased a new coral (thought it was a xenia but now I'm not /too/ sure but anyways) and I found another coral like critter on the rock? I tried my best to grab a photo but every time I get too close to it, it hides quickly. I just want to make sure it isn't anything that will harm my tank! It is light brown in color, but looks nothing like Aiptasia. Upon close look, its tentacles kind of branch at the end into v shapes. This is the best photo I could grab, as every sudden movement I make it dashes into hiding.
