Is this even an aquatic plant? "Water onion"

[Sgooosh]

Hello! I got one of these water onions from a pack, and i think they are actually zephyr lilies?
If so, are they able to do good long term half-submerged and turn into more? the bulb and most of the leaves is underwater but like a quarter of it is growing out of the tank.

They are shallow water plants. If you leave the part growing out of water go, It might make it.
