i did not notice it when I bought it about 4 months ago, however I relocated the flower pot a few days ago and noticed it. It has 2 red feelers among the beige color ones. Kinda looks like a Catapillar.
I am not sure if it stung the Goni or not, I really did not inspect it very well, because I assumed the Goni would just be alive that long and I just wanted something in my tank, at the time of sale.
Well, still hard to get a good shot, but very interesting. Doesnt seem to bother your goniopora in the pic. My thought was an anemone, but the red feelers is throwing that off.
Well, I suppose I will just leave it alone and see what happens. As long as it stays on the flower pot I will see if it grows into something that can be identified someday. I do thank all for the input to my mystery pet.
Not sure how to tell this without touching it. Their movement in water flow looks like how buble tip responds. I think the tenicals tips shape resemble the Russian red square church St.Basil shapes, for lack of better words to describe them.
