I have a fairly good size long spined black urchin. He has been in my tank for about 4 months. This morning I came down to find him sitting on a piece of liverock popping out sesame looking seeds from the top of his body. They are falling off onto the rock and CC
. At this point there is probably 100+ of them and they seem to keep coming. His tentacles are still moving, does not seem in distress but he is just sitting on the same rock popping these seed things out. WHAT IN THE WORLD ARE THEY???
I am afraid they are eggs or something and do not want 100's of Urchins, or worse yet to pollute my tank and kill other fish.
What should I do?
