Bucephalandra are endemic to Indonesia and are found on the island of Borneo. They are slow-growing, hardy and are especially well suited to grow attached to hardscape (rock / wood), as in the picture above and below. They can also be grown on the substrate as long as the rhizome is not buried. Due to their flexible light demands, they can be grown in shaded portions of the tank, or in full lighting.
Last 2 photo shows how submerged bucephalandra looked like.
