A new Alternanthera variant. This colourful, well-growing plant is characterised by its vivid pink leaves with lighter-coloured leaf veins. Under water, it has a relatively compact growth habit, comparable with Alternanthera reineckii 'Mini', and it is great as colourful accent in the middle ground or in the foreground, given that it is trimmed regularly. Like most Alternanthera variants, it prefers good light and an abundant nutrient supply as well as additional CO2 injection for good growth and intensive colours.
Alternanthera reineckii belongs to the family Amaranthaceae under order Caryophyllales. The genus name ‘Alternanthera’ was erected by the Swedish Botanist Peter Forsskal. The genus name ‘Alternanthera’ derives from the Latin ‘alternus’ meaning alternating and Latin ‘anthera’ meaning anther, referring to the alternating fertile and infertile stamen of the flower. At present over five different varieties of Alternanthera reineckii are cultured. Among them Alternanthera reineckii ‘Mini’ is a relatively easy cultivar and is the most widespread variety found in trade.
Alternathera Reineckii "Rosanervig" is a perfect plant for small aquarium or larger aquarium as a background plant. It can easily grow in proper conditions with intense illumination and quality substrate. If it is used in small aquariums they can be planted in small groups around the corners of the aquarium to achieve optimal color under the best light. Overplanted should be avoided which limits the swimming space for the fish. It requires high light and CO2 injection which improves the growth rate and overall health of the plant. In this case lighting should be 0.50 watt per liter while CO2 should be 6-14 mg per liter of water. The tank should have good water quality with pH of 6.0-7.0, hardness of 3-8 dGH and temperature of 4C-30C. For optimum growth organic rich substrate and good fertilizer should be added in the aquarium. To get red coloration iron should be added in aquarium. The tank bottom should have a layer of aqua soil powder because it has the smaller granule size which allows the plant portions to be placed into it safely and securely.
