The amazon sword is an extremely popular aquarium plant due to its lance shaped like leaves, and tall growth nature. This plant is an excellent choice for any community setup, as its long leaves provide plenty of room for the fish to swim above, underneath, or through them. The long, wide profile of the leaves allow for any invertebrates to be able to rest on them to either feed, find excess food, or clean off the leaf where algae may be present. This plant is normally planted in the background section of aquariums due to its large size, and when planted near other amazon swords it can give the appearance of a lush, green jungle awaits at the back of the tank.


Once fully established inside of its home it will start to reproduce by sending out adventitious plants at the tip of its leaves where if no action is taken the leaf will fall off and attach itself to the first thing that the roots are able to get ahold of. If there is a strong current inside of the aquarium, the leave might end up near the filter intake or inside of the filter.


The amazon sword will require that there are iron rich fertilizers added to its substrate, as it is a heavy root feeder. Many owners of this plant will make sure that once they find a nice, suitable location to keep it at, they will take an aquarium grade root tablet and place them near where the plant will be placed at. This way the amazon sword will be provided with the iron-rich fertilizers for a good amount of time before the tablet will fully dissolve. Others will add a liquid fertilizer to the water instead, however it won't have as much as an effect as it would if it was near the roots of the plant.
