Anubias
Slow-growing African aquatic plants with leathery leaves. Indestructible, suitable for any aquarium. They bind to rocks and wood, never buried.
Detailed explanation
The most common species: A. barteri var. nana, A. barteri, A. congensis, A. nana petite, A. coffeefolia.
Fundamental rule: never bury the rhizome. They bind to rocks and wood. They grow in any light, without CO2.
The main problem is the growth of algae on the leaves. They are compatible with herbivorous fish (African cichlids, goldfish). They flower in the aquarium with a white spathe.
