Juncus repens really is a delightful plant that grows up to 50cm in the wild however in the aquarium is rarely seen over 30 cm. This plant has 'grass' like characteristics with occasional star looking flowers on the tips. Long wispy green leaves cascading from the centre of the plant.
This plant is capable of growing in low light conditions however it is much brighter and taller with adequate lighting. Looks great planted around large dark rocks.
