They will grow in one .
But, a standard Amazon sword will get to maybe 2 feet if given room
I had one that took up over half of a 90g aquarium and the leaves were on the glass of 3 of the 4 sides.
You need to remember that even if you trim the leaves, the roots will keep growing.
I would maybe do a chain sword in a 3g aquarium.. or maybe a type of crypt.
And, yes, adding ferts would be good... Especially root tabs that have nitrogen/nitrates in them. For any of my suggestions and you should be able to control growth with the amount of light .
