I recently (2 months ago) purchased my first piece of LPS coral for my newish 90g tank which was a torch coral. It was quite a large piece so I decided to break it into two pieces which was quite easy due to the way it was growing. On the smaller piece I have noticed that there is some white stuff growing on one part of the skeleton. Not sure if this is the start of a new head, something else entirely normal or the start of a problem for the coral? Fairly new to the SW hobby and very new to LPS coral so sorry if this is a very basic question, just want to rule out any potential issues as both torches have been doing well so far. Cheers, PS
