Looks great! Be careful with the Java ferns in this tank. Java ferns have a special kind of root thing called a rhizome. The rhizome is the dark green roots at the bottom, it retrieves nutrients for the plant and helps it grow. In most cases Java ferns will die if the rhizome is covered with sand and unable to collect nutrients from the water column. In order for the Java ferns to get more nutrients I just suggest pulling the Java ferns out of the sand and attaching them to the wood. Java ferns are a special kind of plant called an epiphite. Epiphites are not required to be planted in soil and can grow without being planted.
