Echinodorus tropics (Echinodorus parviflorus “tropica”) – aquarium plant of the genus Echinodorus, originally from South America. The “tropic” variety is very similar to the wild form of Echinodus small-flowered (echinodorus parviflorus), but unlike a wild plant it forms a more compact form of growth and can produce chased leaves.

Lighting: the middle one is very strong.
Temperature water 22-30 ° C.
Rigidity – soft – tough
Priming – necessarily nutritious.

Growth rate Average
In the early 80s of the twentieth century, the famous nursery of the Danish company “Tropica” received a batch of aquarium plants with a modified form of Echinodorus parviflorus, grown in Singapore and Sri Lanka. In 1985, the Czech breeder Karel Rataj described this plant as a variety of Echinodorus parviflorus “Tropica”, and since then Tropica has been widely distributed under this name.
Unlike the Echinodus small-colored variety, the “Tropica” variety forms a small rosette in the aquarium, measuring approximately 10 cm in size and looks very advantageous in the foreground. True, he is more capricious and light-requiring.
In submersible (water) form forms a very beautiful, lush outlet. The leaves have a dark green color (the color depends on the lighting and power) and a strong corrugation.
Leaf blades begin almost from the base of the plant.
Emersnaya (surface) form is characterized by the presence of petiole in the leaf and the fact that the leaves acquire a specific marble shade.
From time to time, another species of Ekhinodorus comes across, which is called “Tropica” with a similar “air” form, but in the aquarium it forms a much larger outlet (height 20-30cm), while the leaf stalk remains similar to that of an Emerson form, and the outlet itself is not so compact and is not suitable for the foreground.
Echinodorus tropic relatively undemanding aquarium plant. Like all species of the Echinodorus genus, this plant will happily end up in nutrient-rich soil and clean water. The soil should be fine fraction (1-4 mm) and light, it is desirable to place a good substrate rich in nutrients, including iron, on the bottom of the aquarium, and fill the top with soil.
The general level of soil in the aquarium should be at least 5 cm.
Echinodorus tropics will grow both in low light and very strong. In low light conditions it remains very small and compact.
Water parameters also do not matter much, it can be soft water, and medium hardness; pH: 6 to 8; temperature 21-28 C.
For the successful maintenance of Echinodus tropic, the introduction of CO2 into the aquarium is not necessary, although this will certainly have a favorable effect on the growth rate and appearance.
The most common problem that can occur with the content of Echinodus tropics, is the lack of iron in the aquarium. This problem can be solved initially by placing a substrate rich in iron on the bottom.
You can also add fertilizer tablets or homemade clay balls with fertilizer to the roots of the plant. Additionally, you can make liquid fertilizer in water.
Echinodorus tropica is a rosette aquarium plant, and regular care for it is to trim the old, damaged or dying leaves. Be careful not to damage the rhizome.
Echinodorus tropics can grow out of the water, but to get a paludarium shape, you should start by placing the sprouts in damp soil with leaves outside the water to allow the plant to adapt to new conditions. At the same time, the soil should always be kept moist, and the leaves should be regularly moistened with a spray bottle – they should not be allowed to dry.
This echinodorus breeds lateral shoots that need to be allowed to grow up to 3-4 cm in height before they can be separated from the uterine bush. The appearance of shoots can be stimulated by extending daylight lighting in the aquarium for several hours.
