Hemianthus Cuba (*Hemianthus callitrichoides* ‘Cuba’), often simply called ‘Cuba’, is one of the most sought-after, yet also most demanding, carpeting plants in aquascaping. Its ability to form a dense, bright green carpet resembling a lawn makes it a central element in many competition aquariums. However, to achieve such a result, the aquarist must create ideal conditions, primarily ensuring a high level of lighting and a stable supply of carbon dioxide (CO2).
