Freshwater angelfish are elegant, tropical fish native to the slow-moving rivers and swamps of the Amazon Basin in South America. Known for their distinctive, triangular bodies and long, flowing fins, angelfish are a popular choice for aquarists seeking both beauty and grace in their tanks. An interesting fact about freshwater angelfish is their remarkable parental care. Unlike many other fish species, angelfish form monogamous pairs and are highly attentive parents. They will carefully clean a chosen spawning site, typically a flat surface like a broad leaf or a tank wall, and once the eggs are laid, both parents take turns guarding and fanning them to ensure they receive enough oxygen. Even after the eggs hatch, the parents continue to protect and care for their fry, showcasing a level of dedication rare among fish.
