This delicate, cushion-forming foreground plant is best used between rocks or as a carpetting plant in the foreground. Despite its moss-like growth, the Dwarf Helzine will remain light green and is hence a great companion or, indeed alternative to real mosses, whose colour is almost invariably of a darker shade. Should you want to keep shrimp such as Caridina japonica, make sure not to have more than about one per 20x20cm aquarium footprint. These shrimp will tend to keep this plant down a bit. We don't have any experience regarding other species of shrimp.
