Anubias nana Coin is a new species to th hobby which has very similar traits to Anubias barteri with the main difference being the leaf shape which resemble (sort of) a coin.

Like all anubias they are slow growers and need to be tied onto wood or rock in order to flourish.

Relatively easy to keep and when introducing anubias to your aquarium, it's sometimes worth taking them out of their pots and rockwool and letting them float in your tank for a few days.
This gives them a chance to acclimtatise and often stops them melting
