I bought this plant about 8 months ago from pet smart as an amazon sword plant but it has not grown taller than about 4 inches but has grown to about 10 inches wide, i dose about once every 2 weeks with liquid ferts and add root tabs about once a month, could it be a lighting issue that is making it so this plant isnt growing taller or is it actually not an amazon sword i was led to believe that they grow fairly tall.
