Housing Requirements

Angelfish requires a minimum tank size of 20 gallons. However, a 30-gallon tank or larger is recommended for a single fish or a pair. These fish prefer soft, slightly acidic water with a pH between 6.0 and 7.5. The water temperature should be maintained between 76°F and 82°F.

These fish are peaceful, but they can become aggressive towards smaller fish. Therefore, it’s best to keep them with other peaceful fish that are of similar size.

Feeding Angelfish

Breeding Angelfish

Angelfish reach sexual maturity at around 6 to 8 months of age. During the breeding process, they form pairs and engage in courtship behavior. They may lay their eggs on flat surfaces such as leaves or the sides of the aquarium.

Parents of these fish are known to be attentive to their eggs and will defend them from predators. When the eggs hatch, the parents will care for the fry until they can swim and feed on their own.

Common Health Issues

Angelfish are generally hardy and disease-resistant, but they can still develop health issues if their environment is not properly maintained. Some of the most common health issues in these fish include fin rot, ich, and swim bladder disorder.

Signs of a healthy fish include clear eyes, active swimming behavior, and a healthy appetite. It’s important to monitor your fish for any signs of illness and seek treatment promptly if necessary.
