Anyone have experience with Brazilian Pennywort or Ludwigia repens?? I’m thinking about getting them for the shrimp tank. I think our yard is p much just Pennywort (I need to confirm that ID) so I’m going to check if it’s safe for the tank. No pesticides, etc. I want a small amount of it, floating?

The ludwigia repens looks like it’ll be good, but I have no idea where to get it.
