First two are easy. Ludwigia repens. hard to plant and keep in soil, roots fragile, fish easily uproot. don’t even need roots to plant it. drill a hole in a plastic bottle cap, string the stem through the hole of the face up bottle cap. Plant in sand substrate, when the bottle cap fills with sand it becomes a natural anchor. The stem will spring new roots. The plant will grow to the top of the water. Stays red easily as it grows.
Sorry I meant first two pictures, not first two plants.You said first 2 what is the second one?
Thank you for all the help
Have you ever bleach dipped?
