Why is it when a big catfish like an RTC is in a 600 gallon tank it looks OK, but when its in a pond 1500 gallons or so, it looks cramped...?

its got to be the angle.
even in my pond. i look at my fish and think, "man they could probably use more room" but i could easily put them in a 300 gallon tank together and they would look fine...
idk. just something that been eating at me for about an hour.
