If your mini parrot fish aren't pairing, the first step is to separate them. Next, perform a thorough water change to ensure a clean environment. Wait until the male's forehead becomes noticeably more pronounced and the female appears rounder before attempting to pair them again. This indicates they are more likely to breed. Also, it is crucial to maintain the correct water temperature.
Initially, upon noticing that your parrot fish are not pairing, it's essential to isolate them promptly. Parrot fish, despite their generally peaceful nature, can become aggressive, and separating them will prevent any potential harm from fighting.
Secondly, the existing water in the tank might not be optimal. Therefore, before attempting to pair them again, it’s crucial to perform a complete water change, providing them with a clean and fresh environment. This significantly improves their overall health and prepares them for breeding. The clean water encourages the fish to feel safe and comfortable, which is conducive for pairing.
After a period of individual housing, once they've adjusted to their current conditions, you can reintroduce them in an attempt to pair them once more. This approach enhances the likelihood of successful pairing. A stress free environment is very important for a successful mating process. The isolation allows them to get used to their new habitat before pairing.
Before mini parrot fish lay eggs, the male's forehead will exhibit a slight bulge, and the female's body will become rounder, while both will display stronger territoriality. These are key indicators that they are ready for pairing. During egg incubation, keep the water temperature between 26 and 28°C (79 and 82°F). The eggs should hatch within 4 to 7 days. Newly hatched fry don’t need immediate feeding, after a few days you can begin feeding them yolk water for the initial nutritional supplement. Controlling the water parameters during the breeding cycle is essential.
