Angel fish

Just got this angel fish, will those stripes darken as he ages or stay light. And is it normal to have a round top fin

 

The stripes will lighten and darken depending on his mood. And a round top fin is perfectly normal.

 

My Angel looks like yours. Her stripes fade in and out depending on her mood and whats going on, just as bizaliz3 said

I find that during water changes they'll lighten, and during spawning times, they become dark and broad.
Quite a wonderful phenomenon

 

Its crazy i noticed when light is on he turns almost yellow all the way, when lights off he gets dark black stripes.
