SPS=small polyped stonys, LPS=large polyp stonys. Both have a hard, calcium based skeleton.
Softies have no hard skeleton anywhere (like xenia) although they do have calcium spicules in the coral tissue to supply some rigidity
You could always try removing the fish and see if it helps but I suspect you might have some water quality problems your not (or can't) testing for.
