Freshwater Angelfishエンゼルフィッシュ
Pterophyllum scalareLC— Least Concern
The freshwater angelfish is a tall, laterally flattened cichlid native to slow-moving rivers and flooded forests of the Amazon Basin, instantly recognizable by its long trailing fins. It is the most widely kept angelfish species in the aquarium trade, forms monogamous breeding pairs that guard their eggs together, and has even had its full genome sequenced.

FAQ
- Why does the freshwater angelfish have such a distinctive shape?
- Its body is strongly compressed laterally and paired with long, trailing dorsal and anal fins, an adaptation that lets it slip vertically between plant stems in its native flooded forest habitat. Source
- How do freshwater angelfish care for their eggs?
- A breeding pair lays around 1,000 eggs arranged in a circle on a leaf or piece of driftwood, and both parents take turns guarding the eggs and the fry after they hatch. Source
