Anubias nana 'Coin' is a relatively new cultivar distinguished by round, coin-like leaves that are more circular than the oval leaves of standard Anubias nana. It's a subtle but distinctive variation that adds a different leaf texture and shape to a planted layout where standard Anubias are already present.
Like all Anubias, it is slow growing, undemanding, and tolerant of a wide range of conditions: no CO2, happy in low light, and attached to wood or rock rather than planted into substrate. Shrimp and fish leave it alone, and the tough leaves are highly resistant once the plant has settled.
Remove from the pot, rinse, and attach the rhizome to hardscape. Letting it float for a few days before attaching can help reduce the chance of leaf melt. Do not bury the rhizome.
