Hi guys, so yesterday me and my wife picked up a fully setup 70 gallon tank, even though we already have a 100 gallon we couldn't pass this deal up as it was really good, the previous guy had a lot of these corals in there, probably around over 100 heads split into about little of about 7 or so, some have dead on them some are healthy, but we have so many of these but we dont know the name of these, are these maybe sun corals? Idk, any help would be appreciated, thank you
