Bolbitis heudelotii

Bolbitis Growing & Care Guide

Bolbitis, also known as the Congo Water Fern, is an incredibly elegant, high-class vertical aquatic species native to West African forest streams. Renowned for its spectacular, semi-transparent deep emerald-green feathered leaves, it grows slowly on hardscape and is prized by professional aquascapers for forming lush, wild jungle textures in high-flow, low-tech layouts.

Lighting Moderate Light

Water Parameter Aquatic (pH 6.0-7.0)

Substrate Epiphytic (Driftwood / Rock)

Water Temp 20°C - 26°C

Toxicity Pet Friendly (Non-toxic)

How to Identify Bolbitis

Bolbitis (Bolbitis heudelotii) has key botanical markers. Recognizing these features is crucial for successful aquascaping and thriving growth.

✔
Visual Shape & Growth: Stately vertical bushes of highly-textured, translucent dark emerald feathered leaves bound to wood.
✔
Leaf Morphology: Beautifully divided, feather-like (pinnate) semi-transparent leaves showing a deep, moody dark-green color.
✔
Root & Anchoring Structure: Dark creeping horizontal rhizome producing strong anchor roots that bind to rocks or wood.

Complete Cultivation & Spawning Guide

Follow our detailed scientific water parameters and care guides to keep your Bolbitis thriving.

pH: 6.0 - 7.0, GH: 3 - 10 dGH. Strongly demands soft, slightly acidic, clean water. Stunts rapidly in hard, alkaline water.

Moderate. Strongly benefits from pressurized CO2 injection, which promotes leaf transparency and emerald coloration.

Moderate light. High direct lighting will cover its delicate feathered fronds with spot and hair algae.

Clip away old, damaged, or blackened fronds at the base of the rhizome using sharp, sterile aquascaping scissors.

An water-column feeder. Relies heavily on comprehensive liquid fertilizers; substrate feeding is not needed.

Do not bury the horizontal rhizome! Tie or glue the roots onto driftwood or rocks. Submerging the rhizome will rot the plant.

Optimal temperature is 20°C to 26°C (68°F - 78.8°F). Prefers cooler water; highly sensitive to heat above 28°C.

Enjoys strong current. Steady, high water flow delivers dissolved CO2 and trace minerals to its feathered leaf structures.

Its tough, bitter texture makes it highly cichlid-proof. Safe for community tanks, shrimp, and breeding setups.

Slow growth makes it susceptible to black brush algae. Maintain low phosphates and employ Siamese Algae Eaters.

Best attached in the midground or background. Position near water flow outlets to maximize current delivery.

Common Diseases & Treatment

Rhizome Rot (Bacterial)

Symptoms: The creeping horizontal rhizome turns soft, black, and decomposes, losing all its leaves.

Action: Caused by planting the rhizome in gravel or poor water circulation. Prune rotted parts immediately and keep remaining sections clear.

Opaque Blackening

Symptoms: Leaves lose their translucent green color, turning opaque brown or black and dying.

Action: Usually caused by excessive water temperature above 28°C or hard, alkaline water. Lower the temp and use RO water.

Frequently Asked Questions

Why is my Bolbitis turning black?

Bolbitis leaves turn black under high water temperatures, high pH, or excessive light. Keep water cool (under 26°C) and slightly acidic.

How do I attach Bolbitis correctly?

Use superglue gel or dark cotton thread to bind the creeping green rhizome onto driftwood or lava rocks. Roots will anchor naturally in a few weeks.

Does it need CO2?

While it can survive in low-tech tanks, pressurized CO2 is highly recommended to develop its iconic translucent, deep green feathered leaves.

How fast does it grow?

It is a very slow grower, typically producing one or two new feathered fronds every 2 to 3 weeks.
