Ok I was told that this plant was a Rotala sp. of some type, but after looking at diferent pics I am questioning what it really is. I was going to sell it to someone that wanted some rotala but they said they thought it was a Ludwigia of some type. I didn't think so but i'm far from knowing what i'm doing so please let me know. All I know is that in low light it is green and in stronger lighting is is red. Mine only has red on the crowns.
