im not sure if its a coral i havent added anything coralwise since mid december i think , it almost seems neon green ( almost the same color as the tips of a hammer coral) but it resembles in texture a leather coral and looks like a mushroom that you would find in the woods. i know it probarly could be a toadstool but i didnt see any tentacles / polyps . ill post a pic when i find it tomorow it was actauly stuck in the space between a korilla pump today. has anyone ever found a random coral in thier tank that they didnt purchase
