Congo Anubias problems — and how to fix them
Congo Anubias (Anubias heterophylla) 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.
Algae colonisation
The broad, slow-growing leaves are prime surfaces for algae. Reduce light duration and intensity; introduce algae-grazing fish or snails.
Rhizome rot
Invariably caused by burying the rhizome. Keep it fully exposed and attached to hardscape.
Brown leaf tips
May indicate water quality issues or mechanical damage. Ensure ammonia and nitrite levels are undetectable.
Very slow growth
Normal; one new leaf every 3-5 weeks is typical. Patience is required. CO2 and good nutrition help modestly.
