Bloated Angelfish

[Lefky]

I just recently saw that my Angelfish has a huge bump on the underside of it. Its scales are not falling/bulging out. He now swims near the top of the tank instead of generally being at the middle-bottom sections of the tank. He still eats at every feeding time. I am unsure of what is wrong with him and what I should do.

Are the pictures of the same fish, because they look like different colours?

The swelling is too high up for its stomach so I am going with a tumour, cyst or enlarged organ (liver).

There's nothing you can do for any of those problems except keep the water clean and feed it a varied diet. When the fish stops eating or can't swim properly, euthanize it.

They are the same fish, but this morning it looks like the swelling has gone down.
