Ammania sp. ‘Bonsai’ is best described as a compact, moderate growing version of Bacopa Caroliniana. Plant in small groups and trim often. Cuttings may be re-planted in the group to achieve a more dense group or carpet. At high the tip of the stems may become reddish, at lower light the leaves will become larger and the plant less compact. Ammania sp. ‘Bonsai’ is particularly suitable for nano-aquariums.

True Rotala indica is not very well-known as aquarium plant. At the moment is it labeled as Ammania sp. “Bonsai” and Rotala sp. “Bonsai” as the trade names, but its flowers have helped identify it correctly as R. indica. The name Rotala indica has been known in the aquarium hobby for a long time, but it was erroneously used for the totally different species Rotala rotundifolia. The unique appearance of Rotala indica can best be described as compact miniature version of Bacopa caroliniana. R. indica is a slow grower; under a lot of light, the shoot tips and stems turn reddish. With its straight hardly ramified thick stems and its roundish leaves it is best planted in a group in the fore- or middle ground of a tank. Rotala indica is especially suitable for smaller aquaria, but a large group of this plant may look nice in a bigger tank, too. Good lighting (at least 0.5 W/litre) and an ample supply of CO2 and nutrients need to be made sure. Moreover, R. indica should not be planted in the shade.

There is quite a bit of confusion around the name Rotala indica in aquaristics. The reason for this is, that in 1960, Rotala rotundifolia was imported under the erroneous name “Rotala indica”. Even today, especially reddish forms of the very variable R. rotundifolia are sold as “Rotala indica” in trade.
True R. indica, however, is a competely different species that does not play a very important role as aquarium plant. Only recently, the plant sold as “Ammannia sp. ‘Bonsai’ ” has been identified as true Rotala indica. It was also confused with Lindernia sp. “India”.
Rotala indica is widely spread in the warmer regions of Asia and is very often found as annual weed in rice paddies. It has been introduced into other regions of the earth where rice is cultivated, e.g. in Northern Italy.

The emersed as well as the submersed forms of R. indica differ distinctly from R. rotundifolia.
The leaves of R. indica are 0.5-1.7 cm long. Their emersed and submersed forms do not differ much, they are obovate to spatulate and have an obtuse tip. Typical for R. indica, and another difference to R. rotundifolia, is the “cartilaginous” leaf margin: with a strong magnifying lens or under a microscope it can be seen that the leaf margin is thicker and whiteish transparent (without chlorophyll). The submersed form of R. indica has a strictly upright growth habit, dense foliage, a relatively thick stem and not very ramified. Under sufficient light, the shoot tip is reddish.
The stems of the emersed form lie low on the ground. The tiny reddish flowers appear on short lateral shoots or in the leaf axils along the stem and have very small, inconspicuous petals. In contrast to these, the flowers of R. rotundifolia are quite distinct in upright spikes on the shoot tip.

Rotala indica is a rather slow grower, and in the aquarium it has relatively high demands regarding light intensity and nutrient supply. Its almost pillar-like upright shoots are best planted as larger, individual group of stems of different length in the middleground of a tank.

The Anubias CUP contains within it numerous small portions of young and vigorous plants that must be carefully rinsed using tap water at room temperature and positioned with the aid of tweezers in the foreground of the aquarium.

Buying a Cup, the customer is sure to receive a healthy, vigorous, pesticide-, nails- and algae free product. Within a package there are more portions compared to a common jar or potted plants and this makes it a product with an excellent quality/quantity-price ratio. The growing substrate, unlike the common rock wool, is liquid or gelatinous and is very easy to remove by rinsing the plant with tap water. The seedlings inside are already divided into small, simple portions to be planted in the substrate of the aquarium. The practical packaging contains on the back all the technical data, the scientific name and the chemical-physical parameters for the optimal cultivation of the plant.
Inside the Cup young micro-propagated seedlings are grown on a nutrient-rich liquid or gelatinous substrate. The substrate can be different in color and consistency according to the needs of the plant. Being a hermetically sealed package, the tongue on the cap guarantees the integrity of the product.
