whats this on my rocks

[fredflinstone]

Its only been a month and a half since I started my aquarium. I get this coral mushroom looking things popping up. Can someone please let me know what these are? If they are actually good or bad ones?

Please look for the photos in my gallery.

Thanks in advance

#2&3 are red mushrooms Good, I can't really tell what the first pic is. That's really cool for hitch hickers, most people have to buy them. Enjoy them because you will eventually get more as they grow.

They are mushrooms and are good. The last pic in your gallery( the far right) looks like zoos, without a closer pic I cant be sure.

The mushroom rocks look great! Very purple with coralline and those mushrooms should spread like crazy. You did quite well picking out the pices of rock that have those on them.
