They're growing down in the squishy completely saturated area at the edge of a pond.

I was wondering if anyone knows what they are and if it might be possible they would grow in my open top aquarium. It's a 10 gallon with a 20 watt daylight CFL over it. Pop bottle co2 injector. PH 7 to 7.2 kh 8.

All I have in there right now is Anacharis and Aponogeton. Oh, and a Platy and 3 Bronze Corys. I'm jonesing for some new plants but I don't have no money honey :-)
