Pics and how old are they? Most of my older fish have a greenish haze to them, I think it's just something that comes with their age from sitting in the water.
Did you mean angels because I was thinking about it if you meant angles as in corners (the corners of the tank) then that is just algae and needs to be scrubbed or you need to add some algae remover.

the gold spotting could be velvet but if the fish are not scratching or dieing then I would say it is just skin pigments, natural colouration. The fish looks healthy enough.
