Ludwigia arcuata

The Ludwigia arcuata, commonly known as Needle Leaf Ludwigia, is a vibrant aquatic plant with striking features. It belongs to the Onagraceae family and is native to the Americas. With needle-like leaves that range in color from green to reddish-brown, this plant adds an eye-catching contrast to any aquarium.

Ludwigia arcuata is a fairly demanding plant, making it more suitable for intermediate or experienced aquarists. It flourishes in nutrient-rich substrates and requires moderate to high lighting levels. Carbon dioxide injection is often beneficial for its growth, aiding in the formation of intense red hues. Adequate fertilization and trimming encourage healthy growth and prevent legginess.

In terms of care, the Needle Leaf Ludwigia appreciates water temperature between 72-82°F (22-28°C) and a slightly acidic to neutral pH range of 6.2-7.2. As it grows, this plant often requires routine pruning to maintain its desired form and prevent overshadowing other aquatic inhabitants.

While Ludwigia arcuata may not be the best choice for beginners due to its demanding nature, its stunning appearance and potential for adding depth and color to aquariums make it a sought-after choice for more experienced aquarists.
