ya a trout would like it a lot better with lots of room they have lots of energy and tend to be messy because they dart around alot (at least river trout do) browns are normally less active though but can be very aggressive a lot more territorial so less likely to make a good tank mate but would have a pritty good chance if were the same size and introduced to the tank at the same time.
you should Google trout in the class room you can find some good information
