So new to the forums and new to reefing in general and have 1 question that stands out among the others and that question is what the heck is on this frag plug I bought for 5 bucks from my LFS? I asked for some pulsing Xenia as I wanted something easy for now and they have me a big frag plug with a small bit of Xenia on it and the rest was occupied with what I thought was this coralline algae I have been seeing and hearing about. But it got bigger and has polyps that come out every now again so I’m guessing it’s some type of coral but I have no idea. I Should probably just ask the LFS but I wanted to heard y’alls thoughts on it. Sorry for bad pics but it’s the best I could get on my phone.
