Anubias Frazeri growing on lava rock grown right here in Florida.
Anubias are considered by many aquarists some of the easiest plants to maintain, since their light and nutrient requirements are very low and also because most herbivorous fish will not eat it. This is why Anubias are some of the few plants which can be used in aquariums with African Cichlids and Goldfishes.
Anubias generally prefer subdued lighting and can also produce flowers underwater. In the aquarium they should be placed in shaded areas, otherwise algae will develop on the leaves.
