Echinodorus angustifolius

Helantium bolivianum "Angustifolius" is the modern name. Family Alismataceae – Chastukhovye. Homeland: South America’s central regions.

The appearance of this echinodorus is quite different from that of other members of the genus. At first glance, the narrow, long, bright green leaves resemble the common aquatic plant Vallisneria. But the entire structure of the plant, including the shape and structure of the leaves, is entirely distinct. Its bush grows to a height of 40 to 45 cm. The ideal location for Echinodorus is next to the side wall, where the aquarium’s background is more visible. Aquarists find the plant to be relatively uncommon. It grows steadily in the aquarium all year round and is rather unassuming.

Echinodorus can withstand temperature changes in the water over a sizable range. The ideal temperature range for the plant is between 20 and 28 °C, which is suitable for both tropical and moderately warm aquariums. Though it can grow in soft water, it prefers medium-hard water. Stable growth is only seen in neutral or slightly alkaline water, like with most Echinodorus species. Plant growth is inhibited by an acidic environment. Changing the water on a regular basis is advised, ideally two or three times per month.

For Echinodorus, bright lighting is ideal. The color of the leaves deteriorates in low light: young leaves lose their reddish-brown hue, while older leaves turn a pale green color. The plant prefers natural light, and it benefits most from diffused sunlight.

For artificial lighting, LB-type fluorescent lamps and incandescent lamps are appropriate. For incandescent lamps, the power should be 1.2 W or more, and for the latter, it should be at least 0.4 W per liter of volume. The length of daylight varies from 8 to 14 hours, depending on how bright the lighting is. The lighting should be left on for roughly 12 hours if the power is close to what is advised.

Echinodorus requires somewhat silted soil. You should carefully clean the soil in the aquarium by sucking it through with a funnel if there has been a significant buildup of organic matter. You can place a lump of clay beneath the plant’s roots in the fresh soil. Natural silting in an old aquarium provides plenty of food for the plant. Because Echinodorus has a delicate root system, it is best to use sand and small pebbles as the substrate. A soil layer that is 3–4 cm thick will guarantee that the root system develops properly. In order to stop too much organic matter from rotting, a deeper soil layer needs to be cleaned more thoroughly.

Supplemental minerals are beneficial to the plant, particularly when it is growing and reproducing quickly. Microelements are the first to require attention; Chapter V lists the recommended dose for each. In an aquarium that is rich in plants and not overly fishy, add 5–10 urea granules per 100 liters of water twice a week to prevent nitrogen starvation.

Echinodorus angustifolia reproduces vegetatively in aquariums. Numerous tendrils emerge from the plant and creep along the ground. Daughter plants form on each of them at a distance of 5–10 cm from one another.

Since it is impossible to separate the babies without breaking the whiskers, the whiskers are split into sections, one well-formed plant with five to six leaves remaining on each section. It is not advisable to split the whisker end that still has three or four tiny plants on it. Use glass pins or pebbles to press this whip into the ground.

You can get the seeds of this kind of Echinodorus in a humid greenhouse, where the right conditions will allow it to bloom. Pollination of flowers is done with a gentle brush. Since vegetative plant propagation is far simpler and yields similar results, seed propagation under artificial conditions is not as important.

Echinodorus angustifolia is a simple terrestrial plant to grow. The characteristics of the soil are not particularly required by the plant. Bright, diffused lighting with an air temperature of between 24 and 28 °C is ideal.
