Capuronii Aponogeton

Aponogeton capuronii is a tuberous plant from fast-flowing rivers in southeastern Madagascar, where it is endemic. It grows from a tuber and produces long, crinkled, semi-transparent leaves that reach toward the surface. It belongs to the group of Madagascan aponogetons that are far less common in the trade than the familiar A. boivinianus or A. madagascariensis.

The tuber should be planted with the crown just above the substrate, and a nutrient-rich base helps it establish. Like many aponogetons it may enter a dormant phase where the leaves die back and the tuber rests before sending up new growth. Water movement suits it, mirroring the river habitat it comes from.

Because this species has no profile in the standard reference databases, the care figures here are estimates based on the cultivation of related Madagascan aponogetons. It grows slowly and is considered difficult, so it suits experienced planted-tank keepers rather than beginners. Temperatures of 22 to 28 °C with soft, slightly acidic to neutral water are the reasonable starting point.
