Scientific Name: Pterophyllum scalare

 Breeding Method: Substrate chooser.

 Ease of Breeding: Moderate.

 Introduction: With their triangular bodies and long flowing fins, angelfish are arguably the most recognizable of all aquarium fish. They are easy to keep and come in many color morphs.

 Sex Differences: Can be difficult to dis­tinguish. Mature females have a slight bulge in the belly area when viewed head on; males tend to be larger and their beads are slightly more curved. The male's breeding tube is pointed, while the female's is rounded, but this is evident only during spawning. Many breeders buy a group of juveniles and let them pair off naturally.

 Equipment: Experienced breeders recom­mend at least a 20-gallon high tank with hood; 30 gallons is even better. Add drift­wood and plastic plants to help the angels feel secure, but keep the bottom bare. Prop two or three pieces of slate or slabs of acrylic against the inside tank walls as spawn­ing site. Cover the heater with mesh cover to prevent the angels from laying eggs on it. (Females will attempt to spawn on any vertical surface; there have even been reports of females attempting to lay eggs on their mate's side!) Add a pre-conditioned sponge filter.

 Conditioning and Triggers: Condition the breeding pair together in the spawning tank, feeding live foods such as brine shrimp and blood worms. Change at least 50 percent of water weekly; some breeders recommend up to 40 percent a day. Raising the tem­perature a degree or two or changing up to 75 percent of the water may prod a reluc­tant pair to spawn.

 Spawning: When spawning is imminent, the angels become extremely territorial, select­ing and cleaning a spawning site while chasing other fish away. At this point, remove other fish from the tank to protect them and allow the breeding pair to spawn without disturbance. Spawning often takes place during the evening, with the female swimming over the site, her belly almost touching it as she lays rows of adhesive amber-colored eggs. The male swims behind her, fertilizing them. When spawning is complete, the par­ents will fan water over the eggs with their fins.

 Brood Size: Up to 500, with 200 to 300 being more common.

Breeding Angelfish is a rapid way to build up the number of fish in your aquarium collection. If you are wanting to give some fish to friends and relatives to help them out, angelfish are an in expensive way to gift fish.

Follow the proper diet for the Angelfish, keep the tank clean and in good condition. If you keet the tank clean and follow the angelfish diet you you can expect your brood sizes to be much larger than if your angelfish were kept at a level of of bad nutrtion in an unkempt aquarium. If you are not changing at least half of the water each week then your are doing heavy damage to your angelfish. Keep the tank in clean conditions and change out at least half the water each week.
