Troubleshooting
Lanceolate Anubias problems — and how to fix them
Lanceolate Anubias (Anubias lanceolata) 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 on leaves
The most common problem; slow leaf growth means algae has time to colonise. Keep light low, add algae-eating catfish or snails, and ensure good water flow over the leaves.
Rhizome rot
Caused by burying the rhizome in substrate. Ensure the rhizome remains fully exposed and attached to hardscape, not buried.
Yellowing leaves
May indicate iron or micronutrient deficiency, or too much direct light. Assess both factors; Anubias rarely shows deficiency in well-maintained tanks.
Very slow growth
Normal — Anubias is inherently slow. Even under ideal conditions, one new leaf per 2–4 weeks is typical. This is not a problem to solve.
Brown leaf tips
Can indicate poor water quality, salt accumulation, or mechanical damage. Maintain regular water changes and check water parameters.
