Guys, need your advice. All my corals are doing well (sps, monti, soft, torch, etc), but I just noticed something strange with my JF Solar Flare (got him about a month or so ago). My other sps are encrusting really well at the base, but with this guy I didn’t notice that its base is thinning, looks like its dead (but its not bleached or white). The top of the frag has great color and constant polyp extension. Almost like a stump area of the tree is dead but the top is doing great. What may be causing this? Should I just cut the healthy top and reglue on a plug?
