Update. I thought it was fantastic that my RBTA split into thirds. Little did I know it split into fours. I was selling one tonight to a fellow reefer and the mother colony that I thought was one big nem was actually two. So there were 4 nems that came from the original mother. All are looking fine and are getting huge again. I think I like this situation. Never seen one split into 4 pieces before. Mathew, let me know how yours is doing.
