Why Is Aquarium Sand Critical for Cichlid Health?
According to a study published in the Journal of Fish Biology, cichlids thrive in environments that closely resemble their native lakes, such as Lake Malawi and Lake Tanganyika. These habitats typically feature sandy bottoms that allow for burrowing and foraging behaviors essential for their physical and mental health (Meyer et al., 2020). Using the best aquarium sand for cichlid species helps replicate these conditions, reducing stress and promoting natural behaviors.
