A very easy-care coral to keep, hardy and recommended for beginners. Mushrooms come in a huge range of colors and sizes, with the ones shown a beautiful blue hue (I also have brown, green, red and purple varieties now). They are easy care and don't require much light. Propagation is also a breeze; just make clean slices with a sharp razorblade, and put the pieces pinned back on the rock; voila, four new mushrooms!
