Advice needed for plants (flowering?)

[blackmirror]

Hi,

Sorry, but I cant remember the name for this plant.

On sunday it starts to grow an arrow headed shoot, within a day the growth reached the water surface (3 ft in 1 day!).

I thought it was going to flower, but the arrow headed shoot kept on growing, now it is "looping" on the water surface. And another shoot is starting to grow.

What should I do?

The plant is Aponogeton ulvaceus. Looks like its going to flower shortly.

Cheers

Vince
