Giant Ambulia

Giant ambulia is a much larger relative of the familiar ambulia (Limnophila sessiliflora). Its feathery, finely divided light green leaves form a wide whorl at each node; these whorls can reach 8–10 cm in diameter. For this reason it quickly fills the space in small aquariums; it looks best in the background of aquariums of 100 liters or more. It likes soft water and strong light; in weak light the leaf whorls become smaller and the stems sparse.

• Stems are planted one by one with 4–5 cm between them; the wide leaf whorls should not shade each other.
• The leaves on the lower nodes are removed and the stem is buried 4 cm deep.

• Light: High.
• CO₂: Not required, but beneficial; with CO₂, larger and denser whorls form.
• Fertilizer: Regular liquid fertilizer, especially iron; when lacking, new leaves turn pale.
• Trimming: Stems that reach the surface are cut from the top and replanted. Because debris can cling to the fine leaves, good filtration is needed.
