I guess this where a coral qt system would be a great idea to watch that one or couple frags to see if any negative damage or nothing at all.If they can not be identified correctly how can they be condemned to the bad for the system category I myself prefer diversity in my system rather than the kill everything philosophy .
As my concern if I'm honest is if I leave it in and now I'm nearly stocked full of fish I'm starting to buy few corals every few weeks ,like today I bought 5 frags in total so can soon add upto lots corals in tank and if a bad thing reproduces in tank and kills lots things then that's a bad thing imo so old saying when in doubt throw it out comes to mind.
But I not thrown it out ,as its actually in my main display as my fish qt tank lights not no good for corals so no good in there and I no qt tank for corals so now need decide what to do with said coral as if cut all nubs off where these whatever they are is,I will be left with the smallest ever sps nub lol
I've read in thread I posted above if glue over Hole then they just bore another hole out.
So I may ring lfs up and see if can swap for another of same kind but inspect new piece in great detail first but probably all off same colony anyway ,but I am noticing white at edges of the branches of this green slimer,I did think it was new growth as I seen other sps on pictures the new growth is white .
So on green slimers is the new growth white like mine is ?
Or think whatever is inside is making negative impact making ends die off ?
Here some more pictures of coral at different levels of zoom as didnt get a answer above .
I will see if can google growth on green slimers also to see if can find out myself also
