Diamond tetra Breeding Guide

Breeding Process

Breeding Diamond Tetras (Diamond tetra) can be moderately challenging, but with the right conditions and dedication, it is achievable. Begin by setting up a separate breeding tank to prevent disturbances from other tank mates. The breeding tank should be equipped with a gentle filter and maintain a water pH between 6.5 and 7.5, with temperatures ranging from 23°C to 27°C. Soft, acid water conditions are known to stimulate breeding behavior in Diamond Tetras. Introduce a group of 6 tetras to the breeding tank, with a mix of males and females, to encourage natural pairing. A spawning mop or fine-leaved plants should be used to provide a suitable place for the eggs. Ensure adequate space as females become fuller with eggs. Condition the fish with a rich diet comprising quality foods such as brine shrimp, daphnia, or bloodworms, as a nutritious diet often stimulates spawning. Observe the fish for courtship behaviors, such as the male displaying to the females by fanning out his fins and forming a 'shimmy dance.'

Care of the Fry

After spawning, which usually occurs during dawn or early morning, inspect for eggs deposited on the mop or plants. Carefully remove the adults from the breeding tank to prevent them from eating the eggs, as they do not provide parental care. Eggs will typically hatch within 24 to 48 hours, depending on the water temperature. Once hatched, the fry will absorb their yolk sacs in about three to four days, after which they can be fed. Start by offering infusoria or commercially available liquid fry food. As they grow, introduce micro worms or finely crushed high-quality flake food.

Additional Information

The tank should remain clean throughout the rearing period, with regular water changes to maintain water quality. Avoid strong lighting initially, as the fry are sensitive to bright light. Gradually increase light exposure as they mature. Be patient and attentive to the water parameters and health of the fry. Diamond Tetra fry tend to grow at a steady pace and can be added to the main tank once they reach a sufficient size to avoid being predated upon.
