Plant question on trimming

I have a dwarf aquarium lily. It has grown great since I planted it.
And now one leaf is just under the surface and curling in on itself. I guess that's what you call melting? But it is not directly under the light.
It has another leave starting upwards and that leaf is halfway there.

Do I trim? Do I let it go? Will it open once it reaches the surface?
And if I do trim, do I follow the stem down as low as I can and snip it there? Will another grow?

Thanks for any help.

 

Melting usually refers to a plant doing poorly for a while after being introduced to a new environment. If yours has been doing well it's probably something else.

I know some plants have different leaf structure depending on how close it is to the surface of the water, or if it's out of the water instead of submerged. Water wisteria and Amazon swords are two that come immediately to mind. I'm afraid I don't know enough about aquarium lillys to say if they do that. Someone else probably will.

Here's what it looks like.

 

If you're talking about the leaf up near the surface, it looks to me like it's bolting to the surface. Lilies will send those curled up leaves to the top, and they uncurl once there as floating leaves.

If, on the other hand, it started uncurled and now is curling up, I don't know.

 

The leaf near the surface started out like the leaf below it, uncurled. It only curled once it was close to reaching the surface.

I Googled the answer on trimming, but could not find an answer to why it suddenly curled other than it might have seeds and they curl to protect the seeds, but mine never had a flower on it so I'm not sure.

I don't think it's seeds. The seeds come from the flowers, not the leaves. Given it curled after being uncurled, I would guess there is something stressing it. But, I don't know what that would be.

 

The one below it curled as it reached the top, too.
No biggie. I'm going to trim them anyway. They keep growing after reaching the top and it's one long stemp with a curled leaf on the end blowing around in the current. It would be nice if the stem simply stopped growing.
