Your baby fish can leave the breeding box once they are large enough to not be eaten by other fish in the tank. This typically occurs when they are about 1 inch in size. It's important to monitor the behavior of the other fish in the tank to ensure that they will not harm the baby fish once they are released. Additionally, make sure that the baby fish are strong and healthy enough to survive on their own before releasing them into the main tank. **

It's important to check with the relevant government agency or employer to understand the specific calculation method and eligibility criteria for parental leave pay during unemployment. **

In many cases, sick leave policies do not allow for retroactive sick leave in case of illness. This means that an employee must notify their employer of their illness and request sick leave as soon as they become aware of their need for time off. Retroactive sick leave is often not permitted because it can be difficult for employers to verify the validity of the illness and the need for time off after the fact. Additionally, retroactive sick leave policies could be open to abuse by employees. It's important for employees to familiarize themselves with their company's sick leave policies to understand the procedures for requesting time off due to illness. **
