Beautiful green hair algae in a guppy aquarium

Green hair algae are super hardy plants. Although many people dislike them in aquarium, I observed that they are very beneficial for guppies. They look beautiful too! In this 35 gallon aquarium, I simply let green hair algae attached on branches (they can also attached on glass wall and gravel). I have kept the bule-red hybrid guppies for more than 6 months in this aquarium, and the guppies seem very happy and have produced many babies.
Green hair algae grow very fast, I need to trim them every 2-3 weeks (this might be a disadvantage).
