Breeding fish
Information about Breeding Angelfish
It is usually very hard to distinguish a female Scalare form a male one, since the look very similar. Most Angelfish keepers are actually unsure of the sex of their fish until they notice which one is laying the eggs and which one that is fertilizing them. If you watch your Angelfish closely right before the spawning commence, you will however notice a small difference in the size of the papilla between the sexes.
Your Scalare will usually need to become at least 5 cm / 2 inches before they are mature enough to spawn for the first time. If kept on a suitable diet, this will happen when the Angelfish is between 8 and 12 months old. To induce spawning, you should keep your Angelfish in an aquarium that is large enough and not overcrowded.
If an Angelfish suddenly displays a bulging belly and a more aggressive behaviour, it is probably a gravid female Angelfish. Two Angelfish grooming each other is also a typical breeding behaviour.
The Angelfish eggs will be deposited on the spawning slate and placed in very neat and evenly spaced lines. If she doesn’t like the spawning slate, she will deposit the eggs somewhere else in the aquarium.
Several methods are used by Angelfish breeders to protect eggs and fry from hungry adult fish. Some remove all fish except the breeding pair from the aquarium, while other breeders choose to remove the breeding pair instead and place them in a special breeding aquarium.
