Need some fish input

I am wondering if I am pushing the limits on this. This is exactly why I am looking for input. Funny thing in my research they say the minimum for the Emporer is 100GL and the Sohal is 180GL. Is the Sohal a much more active swimmer or something.

Full grown they are both around the same size is what I read.

Never heard of the magnificent angel..any pictures or links? Maybe you are thinking of the majestic?

 

i would assume the tang is much more active. tangs swim many miles a day in the wild(ive been told around 20 miles). most emporers i have seen seem more relaxed and easy going then tang
