This frag was given to me for free, it's a green slimer but it's got a green birdsnest attached on the same plug (came like that). It looks like the slimer is starting to rtn. The birdsnest is actually recovering and coloring up, both came from undergrowth. Should I superglue the flesh or just tear it off and chuck it? I'm new to sps, so not sure if this will spread to other frags. Other frags from the same tank/day are not having issues.
