Question on Dwarf Aquarium Lily

[Frank]

Everywhere that I read, people say to wait until the bulb sprouts, then bury it halfway. But, the directions say that it can be planted halfway; after it sprouted. 

Is it OK to leave the bulb on top of the substrate? Or, must it be planted halfway?

P.S. It looks more like a tuber, to me.

Thanks!

I’ve never buried my lilies. I just leave them on top of the substrate and let the roots anchor themselves in.

Thanks! I would have to do some serious excavation, in order to bury it, where it's going.

I know, tubers and bulbs are so confusing! Bulbs definitely have things like basal plates that tubers (which are swollen stems) do not. The illustration below is of a tunicate (meaning arranged in layers) bulb. But if I remember correctly, lilies are imbricate (meaning overlapping like roof shingles) bulbs.

I left mine on the top of substrate. Its interesting to see the roots finding their way down.

i tend to push them in just a little once they start growing, but even if left to sit on the top of the substrate, the roots will find their way down.

Cool!

Mine will be hidden behind a rock; with the leaves poking up above it. I hope!

Another question:

How tall should I let the sprouts get, before I move it? Do they break off easily?

This is exactly my question!  Got 2 tall sprouts to surface 
(feel like a stud aquarist), now what?
