Common Diseases

Java Fern Melt

Symptoms

Fronds turn translucent, mushy, or dissolve rapidly; usually occurs after major water parameter changes or improper planting

Treatment

Ensure rhizome is not buried in substrate; maintain stable water parameters; remove affected fronds; improve water circulation and reduce organic waste

Algae Overgrowth on Fronds

Symptoms

Green, brown, or black algae coating leaves; reduced light penetration through fronds; stunted growth

Treatment

Increase water flow around plant; reduce lighting duration; manually remove algae with soft brush; introduce algae-eating shrimp or fish; maintain nutrient balance

Rhizome Rot

Symptoms

Rhizome becomes soft, mushy, or black; fronds detach easily; foul odor from base

Treatment

Ensure rhizome is not buried or in direct contact with substrate; improve water circulation; remove decaying portions with clean scissors; check for excess organic buildup

Nutrient Deficiency (Iron/Micronutrients)

Symptoms

New fronds emerge pale or yellowish; older fronds remain green; stunted growth; interveinal chlorosis

Treatment

Add all-in-one liquid fertilizer or trace element supplement weekly; perform regular water changes; ensure adequate lighting for nutrient uptake
