Name: Alternanthera

Family: Amarantacee

ImmawewergineOrigin and Habitat: It comes from South America and spread to Africa and Asia, the family is Amarantacee is called Alternanthera because the flowers that grow in emergent forms are alternate on the stem, is one of the first red variety to be introduced into the aquarium. Not live in the undergrowth, but on the tropical river banks where the light is always beats, so is a plant with very soft leaves that in adaptation maybe lose. Often produces adventitious roots, this means that the variety in question has not needed nutrients and then stretching them seeking the roots between internodes and nodes, where they should start only the leaves.

MVI_5140.MOV.Immagine004ALTERNANTHERA CARDINALIS: Shows an almost purple color, the leaves are among the largest and can reach 10 to 15 cm in length. It has a fast growth if well kept and is not recommended for small tanks, bear slightly more warmth, also can also stay in a more acidic water, as in nature.

MVI_5140.MOV.Immagine005ALTHERNANTHERA OCIPUS “TF”: It presents a very particular color, from pink to red fuchsia and orange, which depends from offered nutrients.With moore light, the color becomes more strong, presents a very thin and resistant stem from fuchsia color, rich in inflorescences in the form emerged, and very small leaf 5 to 7 cm. Is perfect for growing submerged in the aquarium, it seems almost a “bonsai”Althernanthera, but if not pruned it grows in height up of the water’s edge. Much more resistant than the other and can also be kept in smaller aquariums.

MVI_5140.MOV.Immagine007_2ALTHERNANTHERA REINECKII PURPLE: It has a very bright color that goes in purple, the leaves are very delicate, wide and elongated, but unlike the cousin cardinalis (more easy to grow), leaves grows closer between internode so that in submerged form is thick and lush, but only if all macro and micro nutrients are sufficient.

MVI_5140.MOV.Immagine011ALTHERNANTHERA REINECKII MINI: Has a very narrow leaf less than 0,5 cm wide and a maximum of 2 cm long, has a very tough stems and colored but at the same time very subtle, for each node start many leaves, so in submerged form is more and thick and lush. It grows slightly in height, but we advise to prune all the time, so keep it low and lush. We believe it is an excellent variety for smaller tanks and recommended as a variety of Alternanthera for newbies, as the crop is much easier than other Alternanthera.

Reproduction and moltiplication: They can be pruned and replanted in the substrate by cuttings. If desired we can also use them as epiphytic plants, on driftwood or stones. Alternanthera tend to become high so are for background tank.

Fertilization and substrate: they need a lot of CO2 and very strong and direct light, otherwise the leaves tend to deteriorate, recommend more than 6000° kelvin. They need balanceed iron and copper. For all Althernanthera is better have more then 10 cm of substrate.
