Thanks, that is actually very reassuring, especially as from your posts I can tell you are very knowledgable about angels.your angel appears healthy. golds tend to have little to no coloration near joints(fins etc) where the fin joins the body.
the redness you see is typical of this coloration.
same can be true near inset of pectoral fins.
other blems could be the result of battles or running into things.
I do not see any issues with your angel.
I wish I could get a better picture of the white spots on his fin, they have not really changed at all in the couple of weeks they have been there. The only difference I notice now is that it looks like the edge of the same fin is deteriorating a little, I also noticed him flash against a plant a couple times today. Its strange, I have researched and read a ton over the past few days and most diseases I have read about have more symptoms/faster progression but I can't help feel something is wrong as the clean water is not healing his fin as I would have liked.
I guess all I can do is keep a close eye on him and keep up with the clean water.
