Don I have a rather large colony I am thinking of selling. It is bali cultured and a nice red with deep blue. It is not super bright blue because I do not have a very good skimmer on my tank. It has covered the entire bali plug and grown about 2-3" on each side around it. I have had it for about 10 months and has grown very nicely since the day I bought it. Let me know if your interested and I can send you a pic. Please PM me if intherested. I am not really looking for any more encrusting monit's but some paly's and plating montis maybe.
