Ludwigia arcuata is a popular stem plant used to add colour. However, it requires high levels of lighting and ideal nutrients to reach its bright red potential.
Suitable for background setting.
As with a lot of pigmented stem plants, nutrient levels also influence colour. Aquariums with low levels of nitrogen in the water column may see a deeper red. Care should be taken with CO2 in very brightly lit tanks to ensure no nutrient deficiencies can occur, leading to deformed or poor growth.
