Bolbitis heudelotii var. difformis

Rare, refined, and hauntingly beautiful — Bolbitis heudelotii var. difformis is a miniature variant of the classic African Water Fern, prized for its deeply lobed, translucent dark-green fronds and slow, deliberate growth. A true collector's plant, it brings an ancient, forest-floor atmosphere to any aquascape and thrives when attached to hardscape in cooler, well-oxygenated water.

Overview

Appearance

The difformis variant is distinguished by its smaller, more intricately lobed fronds compared to the standard species. The deeply cut, fern-like leaves are a rich, translucent dark green that glows under aquarium lighting, creating a lush, primordial texture. Its compact size makes it especially well-suited to nano aquariums and detailed hardscape compositions where the standard Bolbitis would be too large.

Water Parameters & Care

• Temperature: 64 – 78°F (18 – 25°C) — prefers cooler water
• pH: 6.5 – 7.2
• General Hardness (GH): 3 – 10 dGH
• Carbonate Hardness (KH): 1 – 2 dKH
• TDS: 100 – 300 ppm
• Lighting: Low to moderate — tolerates low light well
• CO₂: Recommended — improves growth rate and frond quality
• Fertiliser: Benefits from liquid micronutrients; does not require substrate feeding

Planting & Placement

Never bury the rhizome in substrate — attach to driftwood, rocks, or other hardscape using fishing line, cotton thread, or aquarium-safe glue. The rhizome will anchor itself over time. Good water flow around the plant is beneficial. Ideal for midground placement in nano tanks and as a detailed accent in larger aquascapes.

Compatibility

Compatible with all freshwater fish and invertebrates. Safe for shrimp tanks and sensitive fish communities. Avoid housing with large herbivorous fish that may graze on the delicate fronds. Pairs beautifully with mosses, Anubias, and Microsorum for a lush, natural hardscape composition.

Bolbitis heudelotii var. difformis is a rare and rewarding plant for the discerning aquascaper. Slow to grow but stunning in maturity — a living piece of aquatic art for collectors and planted tank enthusiasts alike.
