Aquarium Conditions for Angelfish

Angelfish live in groups in the wild.  Hence, it is advisable to have a minimum of six fishes in a tank. A male and female angelfish will usually form a pair.  Angelfish are also highly territorial and can become aggressive with other Angelfish.  Hence, the tank should be spacious so that each angelfish pair can have their own area. 

Angelfish are also very sensitive to water conditions.  Hence, the water should be as clean as possible.  Do weekly changes of about 50%.

The general aquarium conditions should be
Temperature: 76 to 82 °F (24 to 28  ° C)
pH: 6.5 to 7.5 °F
Tank Size: 30 gallons
