Sprout in my tank! ID needed.

I posted this is in the Reef Discussion section, but I thought it might be better to also post here.

Last night I was doing an after-dark flashlight inspection of my tank when I found a seed that is sprouting!

The seed is about the size of a flattened whole pepper kernel, and it is a light yellow color. The sprout coming out is shaped like a lower case "y". The first shoot is white in color, but the shoot coming off that is green, like it has been photosynthesizing.

I think it probably came in on a recent rock purchase and just didn't sprout until the conditions were right.

It is making me pretty nervous, to be truthful. It has a root coming out of it that appears as if it will be hard to get rid of if this is a bad thing.

Anyone have any idea what this could be? I haven't removed it yet, but it's under tight surveillance!

Look up dictyota, the 'y' shape reminds me of it. You'll definitely want to get rid of it if that's what it is.

Can you get a picture?

I can't really think of any saltwater plantlife that has seeds. If it has a root end and a leaf end then it might be a seagrass. Or maybe a white mangrove. Or either black. One of them has smaller seeds rather than pods like the red mangroves. Macro algaes don't make seeds as far as I know. I think a picture is neccessary.
