Water parameters
Overview
Lysimachia nummularia is a marsh plant that grows in the damp meadows and along the water margins of Europe and Western Asia. Its round, coin-like leaves are arranged in opposite pairs; this is where its English name "moneywort" comes from. In the aquarium, the 'Aurea' form, with golden-yellow to light green leaves, is used most. Because it is by nature a waterside plant, it grows slowly underwater, but it lasts a long time in cool water. At tropical temperatures it weakens over time; for this reason it is best suited to unheated aquariums and the edges of garden ponds.
Planting and Placement
- Stems are planted one by one with 3 cm between them, 3 cm deep.
- It is used in the midground as a light-colored accent in front of dark green plants.
Care and Fertilization
- Light: Medium; the golden color becomes distinct in strong light.
- CO₂: Not required.
- Temperature: Should be kept below 25 °C.
- Fertilizer: Occasional liquid fertilizer and root tabs are enough.
- Trimming: Because it grows slowly, it is rarely needed; tops cut from the top can be replanted.
