What Is This Plant?

Hi,

About 1 year ago I ordered a mixed batch of plants online, I hoped that I had ordered enough so that my silver dollars/severum wouldn't eat them all if I provided them with enough greens and that any they did chew on would be replaced by the growth of my other plants. This plan failed epically.
I was left with one plant (which I would like to know the ID of) which has remained untouched by the fish. Until recently I thought it was some sort of vallis, however I ordered 3 types of vallis online and it turned out the plant wasn't a vallis, so its left me stumped to what it is.

Now the clues:
The plant grew from a bulb
It has very long (like 2ft+ now), narrow leafs (about 1" wide)
It grew rapidly

It might be a common plant, but I really have no idea what its called and would like some more.

Thanks.

It sounds like an onion plant (Crinum thaianum)

Wow, thanks for fast reply. Yep that certainly looks like it, I'll have to order more
I can't get over how big this plant's leafs are. Its in a Vision 260, which is has about 20" of water in it. From the bottom to the end of the leaf, it stretches to the top of the water, floats to the other side of the tank (its planted in the middle) and wraps around there, so there has to be atleast 40" of leaf on it!
