About the mushrooms, the ones that I'm looking for have a white mouth and some one spots on them. Also when new ones grow they start off as Emerald green and then turn color. You can see a new one growing by looking at the bottom left of the picture, you'll see they start off as a different color.
I have an interesting mushroom. Now it is green background and red spots and looks mostly red. Sometimes it looks blue but not lately. I have one about the size of a quarter and another that is about 3-4 times bigger and is now shaped like an umbrella. $8 for small one and $15 for large one. Picture is of the large one but it is much bigger now . The baby is about that size. http://www.manhattanreefs.com/forum/sale-trade/80635-mushroom.html
