  • Set up the tank:You have to set up the tank that will accommodate your breeding angelfish. Try to choose an above 20 gallons tank for the easy and convenient pairing of your fish. Angelfish will not breed in cramped quarters. Therefore, you should ensure you get a tank large enough to accommodate them.
  • Set the pH of the Water:The right pH of water is necessary for the breeding of your angelfish. Angelfish will not breed in waters with extreme pH values. Ensure the aquarium water pH falls between 6.0 and 8.0 as they prefer slightly acidic, or basic waters.
  • Set the watertemperature: The water temperature is also essential when preparing a tank for your angelfish. Angelfish are very hardy and will tolerate a wide range of temperatures during breeding, but they will do best in waters with adequate temperature. The temperature of the water should range from 780F to 860F.
  • Set a good filtering system:You also need an excellent filtering system in the tank for your angelfish to breed conveniently. Angelfish are ideal for strong currents. Therefore, you should be careful about choosing a high flow filter for the tank, which could tire them out easily. You can use a gravel filter, sponge filter, or both, which will allow enough energy for your fish and also prevent the sucking of small fry into the filter.
  • Feed them properly:This condition is also vital, as an ill-fed angelfish will produce no good eggs. They are not a very picky kind of fish when it comes to food, so they won’t give you much stress on what they will eat. Ensure you feed them at least 2 to 3 times a day.
