I have no idea what the white sponge looking thing with spines is. It appeared on my live rock 2 months ago and has been growing slowly. For size comparison, a Firefish can be seen to the left. Sorry if the focus is not great, I need a better camera. It is Fiji rock and has quite an abundance of life including sea squirts, q-tip sponges, many various worms, random small bugs, and limpets.
Is the spiny fuzzy thing good to have, a pest, or a straight up killer?
