Natural sunlight provides important benefits for Cichla temensis, including support for vitamin synthesis and overall physiological health. Exposure to sunlight helps regulate circadian rhythms and can aid in vitamin D–related processes, which support calcium metabolism, bone structure, and muscle function. Sunlight also enhances immune response, appetite, and activity levels, while promoting fuller, more vibrant coloration through improved nutrient utilization. When offered in controlled amounts, natural light closely replicates wild conditions, contributing to stronger growth, better vitality, and long-term well-being in temensis.
