So I just set up a new tank on Wednesday and I noticed this hitchhiker inside one of the live rock crevices. It's a tan colored disk, with round with zig-zaged edges, and in the exact center no more than 6 tentacles. It seems to inflate/come out during the day and at night reduces to something barely visible within the rock. Any one know what this might be? I have attached photos of it during different times of the day. Any help is appreciated!
