Description

The Half-Black Angelfish (Pterophyllum sp.) is a selectively bred variant of the popular angelfish, known for its striking appearance. Originating from the Amazon basin in South America, this species was developed by breeding wild-type silver angelfish with a recessive gene that produces the characteristic half-black coloration. Due to the difficulty in breeding and raising these fish, they are rarer and more sought after in the aquarium hobby.

Aquarium Care:
The Half-Black Angelfish thrives in warm, temperate waters (79-83°F) and prefers soft, slightly acidic conditions, similar to its natural environment. It does well in tanks of at least 30 gallons, with plants and driftwood for shelter. These fish are territorial, especially in groups, and can be kept alone, in pairs, or in groups of six or more. They are generally compatible with other community fish if the tank is large enough, but caution should be taken with fin-nipping species. They are sensitive to water parameter changes, so consistent conditions are important.

Feeding & Nutrition:
Omnivores, Half-Black Angelfish eat a variety of foods including bloodworms, tubifex worms, flake, pellets, and frozen food. They should be fed small amounts twice a day, ensuring they consume the food within 5 minutes. They may require more frequent feedings if housed with faster swimmers. As they grow, they may prey on small fish such as neon tetras or mosquito danios.

Breeding:
To breed Half-Black Angelfish, both parents must have the full half-black pattern. The fry must be raised in specific conditions (warm water at 80-82°F) and fed appropriately to produce the desired coloration. The environmental parameters and consistent water quality are key to successful breeding. Proper care ensures the fry develop the characteristic half-black pattern, making this fish highly prized for its rarity and striking look.
