I Aquired an unknown Coral from a local reefer who wasn’t having much luck with it growing and i happily brought it home and it’s grown about double the size in the last 2 months. I was told it was found on a mixed rock from Australia. If anyone knows what it is for sure it would be a huge help but I’ve sent videos and pics to all the Pros and nobody knows for sure which is why I find it so interesting. A few of the common guesses is a BowerBanki or something that polyp ejected and survived.
