Generally requiring a weak bleach solution (!) to kill it, this is one of the more difficult aquarium algae to remove. It is usually first noticed on plants but it can extend on hardscape materials like rocks and wood.
This aquarium algae belongs to the red algae family and it usually grows on the edges of plant leaves and aquarium wood and rocks, forming very dense patches which look like a beard, hence the name BBA (Black Beard Algae).
Its color varies from bright green to blue-green, all the way to a more darker green.
Among the aquarium inhabitants, the Siamese Algae Eater (Crossocheilus oblongus) enjoys nipping at it.
