Using terrestrial plants emersed from aquarium tanks has several benefits:
- They give a very nice look and feel to the tank, specially if you are going for a nature aquarium style
- They can absorb excess nutrients, ammonia, nitrites, nitrates ... etc. very fast from the tank which is very beneficial on the fish health
- Their roots can be a good hide out for baby fries and sick/shy or bullied fish
- Many users can depend mainly on terrestrial plants and forget completely submersed ones
- Algae can't infect these plants because most of the plant (except the roots) are in the air
- They can be used as air purifier as well
- They get their CO2 directly from the air so no need for CO2 injection
