Help with angelfish!

[Bic31]

I have one angelfish in a community aquarium. About two days ago it stopped eating and started to become aggressive towards the other fish mostly at feeding time. Today I noticed it's papilla was larger than I remember. The angelfish has taken to one side of the tank and chases away any fish that comes near. I would consider this maybe a breeding thing but it's the only angel. Any advice or help would be greatly appreciated.

Sounds like a maturity thing. What size is your fish?

 

[Bic31]

It is fairly large.

How big is the tank?

How big is the tank?

I have a 75 gallon tank. Today I have a new problem. Just about an hour ago he started swimming erratically, breathing rapidly, and it looks like his scales are shimmering. For lack of a better description they look like they are loose (near gills). I am worried that I may not have an angel when I wake up in the morning. Help!

For a lack of better description it looks like they are loose and shimmering. I am worried when I wake up I won't have an angel anymore. Help!

I would remove the weak angelfish and let him recover in a different tank right now.
