Why do my angelfish fry keep dying?

The loss of angelfish fry can be distressing, and there are several potential reasons for their mortality.

Poor water quality

Inconsistent or poor water quality is a leading cause of fry mortality. Ammonia and nitrite levels must be kept at zero, and nitrates should be maintained at a safe level through regular water changes.

Inadequate filtration

Inadequate filtration in the fry tank can result in a buildup of waste and debris, leading to poor water quality. Ensure your filtration system is suitable for the tank size and stocking density.

Insufficient oxygen

Fry requires well-oxygenated water inadequate aeration or surface agitation can lead to oxygen deprivation. Use air stones or sponge filters to ensure proper oxygen levels.

Poor feeding practices

Overfeeding or feeding inappropriate foods can lead to digestive problems and illness in fry starting with proper fry foods like newly hatched brine shrimp or commercial fry food.

Inadequate temperature

Maintaining a stable and appropriate temperature is crucial for fry, sudden temperature fluctuations or incorrect temperature can stress and harm them.

Disease and infections

Fry are vulnerable to diseases and parasites, isolate and treat any sick fry promptly to prevent the spread of illness.

Stress and aggression

Adult angelfish, including the breeding pair, can become aggressive and prey on their fry separating adults from fry after breeding to prevent this.

Genetic factors

Sometimes, genetic issues can result in a weak fry that does not survive. Breeding healthy angelfish with strong genetics can reduce this risk.

Inexperienced breeding pair

Inexperienced angelfish breeding pairs may not provide proper care to their fry with more breeding attempts, they tend to become better parents.

Inadequate quarantine

If introducing new fish or plants into the aquarium, ensure proper quarantine to prevent the introduction of diseases or parasites that can harm fry.

Prevent Angelfish Fry from Dying

The following are the points to prevent angelfish fry from dying:

Maintain excellent water quality

Regularly test and maintain optimal water parameters, and keep ammonia and nitrite levels at zero- frequent partial water changes are crucial.

Provide adequate filtration

Ensure your filtration system is adequate for the tank size and stocking density. A good filter helps maintain water quality.

Improve oxygen levels

Enhance oxygenation with air stones or sponge filters to provide sufficient oxygen for the fry.

Select suitable foods

Begin feeding with appropriate fry foods such as newly hatched brine shrimp or high-quality commercial fry food, and offer small, frequent meals to avoid overfeeding.
