Funny, I haven’t had one of these posts in a long time. Latest additions to my tank was about a month ago 1 yellow watchman goby and a yellow eye tang. The tank has been about 100 lbs of live sand and live rock. I upgraded from a 36 bow front to a 75 about 18 months ago and the tank has just been running in with only a blasto frag and gha for a year. Tonight I found this on my glass and I’ve never seen it before. There seem to be thin white / translucent feeders extending from each branch. I circled it to see if it’s mobile, I’m guessing it is since it wasn’t on the glass this morning.
