Competing For Light

[mattyeatsmatts]

Hey Guys

So after being away for the weekend I've come back to see quite a lot of growth from my plants(which is great). On Friday I bought some Frogbit for the surface of the tank and its doing great also.

Now that I have the frogbit on the surface the current of the water means it is drifting above my Japanese cress, and creating a low light spot. Will the cress find its own light or will I have to intervene?

Does it move over it and stay there or move over then drift away and back again? If it keeps moving all round it will be ok, think of it like clouds moving in front of the sun if not and completely shadowing it, keep an eye, see how it dies and if needed move the plant that's shadowed.
