The Boss (big angelfish)

Question
I have a 55G long. 1 huge angelfish, 2 pretty big black ones, and 2 medium sized gold ones. The 5 angelfish naturally fight all the time. The fighting started a month after adding the big guy. Last night I tried to feed the fishes and I noticed my black angelfish were the only ones who really dug in. Then I noticed my big angelfish is NOT EATING AT ALL. He has a HUGE appetite but didn't eat at all last night or today, plus the angel-war has stopped in the tank.

Something is definately wrong. I look very closely at his body and notice nothing but two VERY VERY tiny white spots on his fins which could be fungal infections. I've been treating with melafix and pimafix. Unfortunately this decreases oxygen in the water so they all hang out in top of the tank. Plus I've never had a fish stop eating from a tiny fungal infection. What should I do? I love this guy...

Answer
Hi Arya,
 Two tiny white spots are not a fungal infection.  I would stop treating with anything and do lots of water changes, as in a 25% water change today, another tommorrow and maybe a third change the next day.
