Troubleshooting
Anubias congensis problems — and how to fix them
Anubias congensis (Anubias congensis) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Rhizome rot
Burying the rhizome in substrate causes rot. Keep it exposed on hardscape and excise any soft, blackened sections.
Algae on long leaves
The broad, slow leaves collect green-spot and beard algae under strong light. Moderate lighting and increase flow.
Leaf melt on transition
Emersed-grown plants may shed leaves when first submerged. Keep the rhizome and allow new aquatic leaves to develop.
Slow or stalled growth
Indicates low water-column nutrients. Apply a complete liquid fertiliser and consider modest CO2 to spur growth.
