Anubias Hastifolia is a unique variant of Anubias which can be distinguished by the arrowhead-shaped leaves.  Like other Anubias it can grow in both aquariums and terrariums either submerged or emersed.  It has slightly longer stems compared to smaller variants such as Anubias Nana or Congensis which makes it suitable for the midground or background of an aquarium.
Like other Anubias, this variant is a flowering plant that grows best when the rhizome is attached to a hard surface such as wood or stones.  They have low to medium light requirements and can benefit from regular fertilization. CO2 is not necessary but can promote faster growth and more robust leaves. Since its a slow grower, the leaves are susceptible to algae growth if placed under high lighting.   
Propagation is easy and straightforward; simply cut or pull apart rhizomes to be replanted. Make sure to keep the rhizomes above your substrate or the plant can begin to rot.  
Notes:
Anubias are strong plants that can thrive in a variety of environments.
These epiphytes can be planted into substrate or attached to hardscape.
Do not make drastic changes to the aquarium. Unstable parameters will result in melt and rotting of the aquarium plant.
Please be sure to remove this plant from its pot. For instructions on how to properly prep aquarium plants, click here.
CO2 injection and quality aquarium soil will yield better growth.
Please research appropriately to ensure your plant thrives.
