I have a 20 g reef it's been running for 3 months now, I got this dragon soul favia a month ago and it's been doing great, a little over 2 weeks ago this little thing started to appear out of the favia, it's been getting a little bigger but no ill effects so far, I was wondering if someone knew what it is and if it's bad for the coral.
