Anyone have any idea what this plant is?
They grow super fast... faster than hygro.

Green Myrio, Myriophyllum pinnatum, is also known as Green Foxtail or Green Water Milfoil.

Looks like Hornwort. Super fast growing weed.

It's not hornwort. Zapins is correct that it's a Myriophyllum and is probably correct on the species as well.

I have to agree with the Myriophyllum although not sure exact species name.

It looks like the Myriophyllum aquaticum "Green" in my tank. A little smaller and not as easy to transform in the emersed form as the reddish standard form of M. aquaticum.
