Tank is pretty easy to care for, I use a sponge prefilter on a Rena 3 that gets cleaned about once every 3 months. I'll pick off dead leaves, but it's easy since they grow out of the water, easy to get too, moss acts as the water conduit for higher growing plants.
There is a lot more Anubias than you can see.
I'm letting the pennywort and Water sprite take over a bit more.
The roots and the shoot of the water sprite are both trimmed, not just the leaves/stem/shoot.
