Is the red that is on the gold angels fins always there? If not I would be worried about bacterial. I don't see the white spots you mentioned...is it just slime coat coming off?
Also, the way they are at top of tank looks like they need more oxygen...increase the surface agitation somehow....lower the water level so there is more splashing if you have too.
