Eric, I did a little research and seems as though tulip anemones might be a type of mojano. Most of the newer links sight them as a OK to have but something that needs to be keep in check. Just about all of links seems match what Greg mentioned regarding the reduced sting. From reading it sounds like lots of nano reefer have them.
Angel, you can most certainly have a group of them. Send me a PM and we will work out the details.
