Anubias Congensis (Detail)

Anubias Congensis is rated as a low-light plant. Low light means a basic aquarium LED is usually enough, and adding much more light without matching fertilizer tends to feed algae on the leaves before it speeds up the plant. CO2 is not needed for it, and its care difficulty is listed as beginner.

No. Anubias Congensis does not need injected CO2, so it suits low-tech tanks without a CO2 system. It is a low-light plant. For nutrients: tolerates inert substrate with occasional root tabs. Keep light, CO2 and fertilizer in balance, because raising one without the others is the most common cause of algae in planted tanks.

Cut healthy stems and replant. Some species split rhizomes. When dividing a rhizome, keep several healthy leaves on each piece and plant or attach it so the rhizome itself is not buried in the substrate. New growth comes in fastest when the tank matches its needs: low light, with CO2 not needed.

Yes. Anubias Congensis is listed at beginner difficulty. It needs low light, CO2 is not needed, and for nutrients: tolerates inert substrate with occasional root tabs. Stable light, nutrients and water changes matter more than any single product. Check these needs against your current setup before buying.
