Altum angelfish Breeding Guide

Breeding Process

The Altum Angelfish, renowned for its elegance and beauty, is a challenging species to breed in captivity due to its specific care requirements and natural habitat needs. Breeding usually occurs in a well-monitored environment replicating the fish's natural riverine conditions. It is recommended to introduce a group of Altums into the breeding tank and allow pairs to form naturally. During breeding periods, Altum Angelfish exhibit increased territorial behavior and heightened aggression, which necessitates careful handling and observation. To facilitate breeding, provide a spacious tank with at least 75 liters per fish, and ensure water conditions are optimal. Maintain the water temperature between 26°C to 28°C, slightly higher than the standard range, to mimic breeding conditions. The tank's pH should be stable, ranging between 6.5 and 7.5. Include vertical surfaces such as broad-leaf plants or slate as potential spawning sites, as Altum Angelfish prefer to lay eggs on clean, smooth surfaces.

Care of the Fry

Once spawning occurs, the eggs adhere to the chosen surface. Both parents typically guard and clean the eggs actively. Provide the breeding tank with subdued lighting to replicate the dim conditions of their native habitat. Eggs usually hatch within 48 to 72 hours. Post-hatching, the fry will remain attached to the spawning surface or settle on the tank bottom to absorb their yolk sacs for nourishment. By the end of the first week, fry will become free-swimming and will require small, frequent feedings. Start feeding them with infusoria or freshly hatched brine shrimp, gradually introducing finely crushed flakes or micro worms as they grow.

Additional Considerations

Maintain pristine water quality by performing regular water changes, taking care to match the new water's temperature and pH with that of the tank. Altum Angelfish parents are highly protective of their young; however, if aggressive behavior leads to significant stress or threat to the fry, removing the fry to a separate rearing tank may be necessary. Equip the fry tank with gentle filtration to avoid accidental fry intake, ensuring they grow in a safe, nurturing environment.
