i have a red mushroom rock in my tank that is covered in them. they are big and look very healthy and normal. over the last couple weeks there are all these red things that look like mushrooms and they are growing everywhere. Making the tank very ugly. are they in fact mushrooms? or what would they be. They are about the size of an eraser maybe a bit smaller and there are hundreds of them all over the tank. On the sand rocks glass and even the snails and crabs. Please give me some opinion of what they are and what to do.
