Bacopa australis, like other Bacopa species, is an easily cultivated aquatic plant well-suited to beginners. It is native to South America and relatively new to the aquarium hobby world.
The small, round leaves can be distinguished from those of other similar varieties (like Lysimachia or Micranthemum umbrosum) by its unique wavy blade. In a well-lit aquarium, the leaves may also take on a subtle copper or reddish color.
Although not strictly required, good lighting (2 - 4 watts/gal) and CO2 supplementation will encourage lush growth. When healthy, B. australis will spread horizontally as a densely-branched, almost bush-like species.
Hobbyists can trim this plant regularly to promote thick, lateral branching, but lower stems can rot if the plants are grown too densely. Cuttings may be replanted in order to propagate.
