Overview
Bolbitis heteroclita 'Difformis' is a miniature, irregular-leaved form of a fern species common in Southeast Asia. Its leaves are very small, light to medium green and look randomly lobed; its name comes from this "misshapen" structure. The plant usually stays at 5–10 cm and forms a dense, finely textured clump along its rhizome. It is used in nano aquariums and for detail between stones in larger layouts.
Planting and Placement
Do not bury the rhizome. Tie it to a small stone or piece of driftwood with fine thread or fix it with gel glue. The roots attach within a few weeks.
Care and Fertilization
- Light: Low to medium.
- CO₂: Not required, but supports growth.
- Fertilizer: Liquid fertilizer is enough.
- It grows very slowly and its leaves are small, so algae can easily cover it; gentle flow and algae-eating shrimp help. The rhizome is propagated by division.
