You are correct mate, nice one!
Not sure weather to move it lower down now, its surrounded by sps frags which I only introduced 1 week ago
Just read about 5 inch sweeper tentacles and its growing like a weed
In the states that one is quite common and $25 will buy you a nice size mini colony in my experience. Not sure about the UK though. Nice coral any way about it but yes you have to watch out for the sweepers. mine colors up best in lower light
Be careful keeping it around peaceful SPS like Montis or Acros since they are incredibly agressive, grow blazingly fast, and have HUGE sweeper tentacles. That acro to the left is well within stinging range. They can have sweepers that are 6-8" at the size yours is now. Mine is slightly smaller and had to be put in a "canyon" because it had 5-6" long sweepers that have a very strong sting.
