Coffee-leaf Anubias problems — and how to fix them
Coffee-leaf Anubias (Anubias coffeifolia) 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
Slow growth and strong light create ideal conditions for algae. Reduce photoperiod, introduce algae-eaters (e.g. Otocinclus), or manually remove algae with a toothbrush.
Rhizome rot
Caused by burying the rhizome in substrate. Always attach to hardscape and keep the rhizome exposed.
Yellow leaves
Indicates iron or micronutrient deficiency. Dose a liquid fertiliser containing chelated iron.
Slow growth
Normal for Anubias; one or two new leaves per month is typical. CO2 supplementation and adequate nutrients can accelerate this slightly.
