The Majano Problem - The problem the majano anemone presents is that while by itself it appears to be a rather docile creature, minding its own business, it has a disturbing tendency to divide and conquer. In other words it is extremely invasive. One can have an attractive saltwater aquarium, complete with a coral reef and a majano anemone or two, and before long, everything is covered with the anemone. So, it's little wonder that it is an undesirable creature to have. Not only undesirable, but in the view of many, very difficult to bring under control or get rid of.
