i have some Anubias barteri nana (Anubias) in my tank... i wanna know if i have to plant these under my gravel or leave it just under the gravel and let it send out it's own roots. i attached it with some lead...
the roots doesnt needs to be in the gravel, the Anubias barteri nana can even be planted out of the water as long as the roots and rhizome is wet it will grow.
I have some attached to a piece of wood growing out of the water, the growth out of the water is very high.
It will grow best with the roots in the gravel, but if the roots aren't long enough to bury, you can let the rhizome float a few inches above the substrate, and it will send down roots.
