I recently bought some rock with mushroom corals on it (about 3 weeks ago.) Since that time, this extra coral has started to grow. I didn't buy the rock for this, it was bought for the blue mushrooms, but this anemone type coral is, what I am hoping, an added benefit!? The downside is that is it competing for light and space on the rock agaist the mushrooms, and winning. Please help me identify. If it is desired, what kind of flow, food, etc... Thanks for the help!
