Angelfish usually become capable of reproduction after being raised for 10 months. Some individuals that mature sexually earlier may be able to reproduce when they are a little over 9 months old. The best breeding season is usually in spring, because at this time the water temperature is suitable and there is sufficient sunlight, which is beneficial to the reproduction of angelfish. To ensure the success of reproduction, it's crucial to choose older and more mature angelfish for pairing, as younger angelfish may not have good breeding results.
During the breeding process, it's necessary to pay attention to keeping the conditions such as water quality, temperature and light stable. In terms of water quality, angelfish are suitable to live in slightly acidic soft water. The pH value should be between 6.5 and 7.0, and the hardness (GH) should be between 3 and 6. The water temperature should be kept between 26 °C and 32 °C. Besides, choosing healthy parent fish for pairing is also the key to success.
The reproduction cycle and conditions of angelfish are of vital importance for their successful reproduction. By providing a suitable living environment and careful management, we can ensure that angelfish grow up healthily and reproduce successfully.
