Types of Angelfish

Freshwater Angelfish
Freshwater angelfish (Pterophyllum scalare) are the most popular aquarium varieties. They are prized for their tall, triangular bodies, long, flowing fins, and vibrant color patterns. Ideal for tropical freshwater tanks, they thrive in community setups with calm, non-aggressive tank mates.

Saltwater Angelfish
Saltwater angelfish belong to the family Pomacanthidae and are often brightly colored with striking patterns. Found in coral reefs of the Indo-Pacific, Caribbean, and Atlantic Oceans, they require stable marine aquarium conditions and specialized diets to maintain health and coloration.

Dwarf Angelfish
Dwarf angelfish, including species like the Coral Beauty (Centropyge bispinosa) and Flame Angelfish (Centropyge loricula), are smaller, easier to care for, and highly decorative. Perfect for reef tanks, they are hardy and adapt well to smaller marine setups.
