I do love an Anubia wall, I'm still gutted I lost mine to BN (burrowing nematodes). Had a Buce wall also (really a half wall sized slab of Mopani) lost that too (not completely) but thankfully not to BN. I planted my Anubias a little too close together, you have a decent amount of space between so when it grows in it should look less tangled than mine did.
