I am so sorry for you and your fish. I know you must be frustrated and angry with your father. Maybe you can hide the food somewhere he can't find it from now on? Does he understand that he made a mistake? Hopefully he sees now that you know more about how to care for your own fish than he does and will let you handle it on your own in the future. Luckily you saved some. It can be hard dealing with someone who doesn't trust that you are capable. I wish you well!
