I've had this jewel cichlid for a while now. Recently I added a green phantom pleco. Of the eighteen fish in the tank only the green phantom and the jewel are showing visible signs of whatever this is. It looks like ick to me but protrudes two to three mm from the skin. The jewel does not have visible redness around the spots. The pleco does.
