With the potted plant and/or bunch delivery methods, it is very important that the plant is not planted directly with invertebrates. The plant should be soaked for at least one week with regular water changes. The nurseries' source material for these delivery methods mostly comes from Asia. Invertebrates could be harmed when the plant is added to an established aquarium. There should be no problems with a new setup, but you should still carry out regular water changes here as well.

Description

Egeria najas is an undemanding anacharis species that is not yet that familiar in the aquarium hobby as Egeria densa. Like this species, it is native to the southern part of South America (Argentina, Uruguay, Paraguay, Brazil), but its range stretches farther to the north, into the tropical zone of Brazil. This true submerged plant occurs in various flowing and standing waters. The plant has a more delicate appearance than Egeria densa; the leaves are narrower, with clearly visible teeth on the edges. The shoots are densely set with leaves and about 2-3 cm wide.

The Narrow-leaf Anacharis is an adaptable and fast-growing aquarium plant that should be well lit. Nutrient-rich water is very beneficial for its growth, CO2 supply is not always necessary. It can grow floating along the surface but can also be planted into the ground where it anchors itself with few long, unbranched roots. The optimum temperatures lie between 15 and 26 °C; also 30 °C are tolerated, at least temporarily. Egeria najas is more suitable for tropical aquariums than Egeria densa. As well as other stem plants it is easily multiplied by cuttings.

This Anacharis from the subtropics and tropics is versatile and especially recommendable for the initial planting of newly set-up tanks. It is also useful for breeding tanks because it produces a lot of oxygen, takes up excess nutrients from the water column and provides hiding places for the animals. Its deeply green, dense foliage is also decorative in variously planted, rather tall aquariums.

Egeria najas comes from central and southern South America. It occurs partly in the same area as Egeria densa, but is also distributed further north into the tropical zone of Brazil and Paraguay. As a submerged plant it colonises various waters such as lakes and rivers.

The naiad-like waterweed has not been common as an aquarium plant for as long as the dense-leaved waterweed (E. densa). It is, however, an attractive stem plant that makes virtually no demands on the aquarist and also tolerates more warmth than E. densa.

Scientifically, Egeria najas has been known just as long as E. densa; both species were described in 1849 by J. E. Planchon, who established the genus Egeria. Altogether three Egeria species are distinguished today. The third species is E. (read more)
