What Is an Angel Fish
Angel fish, scientifically known as Pterophyllum, are freshwater cichlids native to the Amazon River basin in South America. They naturally inhabit slow-moving rivers and flooded forest areas.
Despite being cichlids, angel fish are generally more peaceful than many other members of the cichlid family.
Physical Characteristics of Angel Fish

They come in a wide range of colors and patterns, including silver, black, marble, gold, and striped varieties.

Natural Habitat of Angel Fish
In the wild, angel fish live among dense aquatic plants, submerged roots, and slow-moving waters. They prefer calm environments with plenty of vertical structures.
This natural habitat explains their preference for tall tanks and planted setups.
Ideal Tank Size for Angel Fish
Angel fish need adequate space to accommodate their body shape and fin length. Taller tanks are especially important.
Crowded tanks can cause stress and aggression.
Aquarium Setup for Angel Fish

An angel fish aquarium should include vertical plants, open swimming space, and gentle water flow. Smooth decorations and driftwood are suitable additions.
Avoid sharp objects that could damage their fins.
Water Parameters for Angel Fish
Angel fish thrive in warm, clean water with stable conditions. Sudden changes in water parameters can stress them and lead to illness.
Regular water changes help maintain optimal health.
Filtration and Water Flow
Moderate filtration is ideal for angel fish. Strong currents should be avoided, as angel fish prefer calm waters.
Efficient filtration helps keep the aquarium clean without disturbing their swimming.
Diet and Feeding Habits
Angel fish are omnivorous and require a balanced diet. High-quality flakes or pellets should form the base of their diet.
Supplementing with frozen or live foods improves coloration and vitality.
Feeding Schedule
Angel fish should be fed in controlled portions once or twice a day. Overfeeding can lead to water quality issues.
A varied diet supports long-term health.
Behavior and Temperament
Angel fish are generally peaceful but can become territorial during breeding. They are curious, intelligent, and interactive fish.
Their calm behavior makes them suitable for community aquariums when properly matched.
Compatibility with Other Fish
Angel fish can live with many peaceful species. Tank mates should not be small enough to be eaten or aggressive enough to harass them.
Careful selection ensures a harmonious aquarium.
