cichlídeos

Cichlídeos are a diverse family of freshwater fish, Cichlidae, found in tropical regions of Africa, Asia, and the Americas. They are characterized by their relatively deep bodies, single nostril on each side of the head, and a broken lateral line. Cichlids exhibit a remarkable range of sizes, colors, and behaviors, making them popular in the aquarium trade.

This family is renowned for its complex social interactions and parental care. Many cichlid species display elaborate courtship rituals, territorial defense, and dedicated guarding of their eggs and fry. Parental strategies vary, including substrate spawners, mouthbrooders, and even some species that lay eggs on leaves. Their adaptability has led to their success in various aquatic environments, from fast-flowing rivers to stagnant lakes.

The M'buna cichlids of Lake Malawi are famous for their algae-grazing habits and vibrant colors, while the discus and angelfish from South America are prized for their striking appearance. Due to their diverse breeding strategies and often aggressive nature, cichlids require specific tank setups and compatible tank mates when kept in aquariums. Their ecological impact is also significant, with some species playing important roles in their native food webs, while others can become invasive when introduced to new habitats.
