I have a 65 gal marine (fish) tank for a little more than a yr. I recently noticed little green balls 1/8" to 3/8" in diameter attached to gravel and on the live rock. I took one to my local shop and they said that it wasn't a good thing and not to pop or break them inside the tank but could not identify them. Any ideas?
