Limnanthemum indicum auct. is a freshwater plant that belongs to the Menyanthaceae family. The plant is native to tropical and subtropical regions of Asia. It grows primarily in still or slow-moving bodies of water, such as lakes, ponds, and marshes.
Light Requirements
Limnanthemum indicum auct. requires moderate to high levels of light for optimal growth. In its natural habitat, the plant thrives in areas of full sun to partial shade. In an indoor aquarium, the plant should be placed in a well-lit area with at least 6 hours of direct or indirect sunlight daily. Insufficient light can lead to stunted growth and yellowing of the leaves.
Temperature Requirements
Limnanthemum indicum auct. prefers warm water temperatures ranging from 68°F to 86°F (20°C to 30°C). The plant has adapted to these warm temperatures in its natural habitat and requires them to grow properly.
