l'm not an expert at this reef thing so it may not be a flame scallop but it really looks like one to me. I have no idea where this thing came from, how long it's been there, or how it's been surviving this long. I'm guessing it was small and just has been growing in that spot for a while, I heard that they were incredibly difficult to keep alive so l've never tried to get one even though I've really wanted one. I've also read that they need immaculate water quality and my water has been dirty since the creation of this tank, nitrates around 25 and it has been higher than that before up to 50 and I have no idea what the phosphates are but I'm assuming they're high too. Hopefully the reef flux that I put in here doesn't kill it. I thought it was a huge aiptasia when I first saw the tentacles peaking out.
