Cabomba Piauhyensis

Vivid, feathery, and strikingly beautiful — Cabomba piauhyensis, commonly known as the Red Cabomba or Purple Cabomba, is one of the most visually stunning stem plants available for the planted aquarium. With its finely divided, fan-shaped leaves in rich red to purple tones, it brings a dramatic splash of warm colour and fine texture to any aquascape.

Overview

Appearance

Cabomba piauhyensis displays finely divided, fan-shaped leaves arranged in opposite pairs along the stem, in rich red to purple-red tones that intensify under good lighting. The feathery, delicate leaf structure creates a fine, soft texture that contrasts beautifully with broader-leaved plants. Under bright lighting, the red-purple colouration is vivid and jewel-like, making this one of the most colourful stem plants available. The stems grow upright and can reach impressive heights, creating a dramatic red backdrop in the aquascape.

Water Parameters & Care

• Temperature: 72 – 82°F (22 – 28°C)
• pH: 6.0 – 7.5
• General Hardness (GH): 2 – 12 dGH
• Lighting: Moderate to bright — strong lighting is essential for maintaining the red-purple colouration
• CO₂: Recommended for best growth and colour
• Fertiliser: Regular liquid fertiliser with iron and micronutrients is important for maintaining vibrant red colouration

Planting & Placement

Plant stems in groups in the midground to background. Trim regularly to encourage bushy, dense growth and prevent the lower stems from becoming bare. The feathery leaves are delicate — handle with care during planting and maintenance.

Compatibility

Compatible with peaceful fish and invertebrates. Avoid herbivorous fish that may damage the delicate feathery leaves. Best kept with small, peaceful community fish and shrimp.

Propagation

Propagate by taking stem cuttings and replanting in the substrate. New roots develop quickly from the nodes.

Cabomba piauhyensis is a spectacular stem plant that brings vivid red-purple colour and fine, feathery texture to any aquascape. Rewarding, fast-growing, and always eye-catching — a wonderful choice for aquarists seeking dramatic colour in their planted tank.
