Dream about fish eating each other is a signal for your need for contact and communication. Perhaps you are letting others dictate your direction or goals in life. You need to come clean about something that has been nagging on your mind. This signals a neglected friendship. You need to learn to question everything.
Fish eating each other dream is fertility and rebirth. Perhaps you need to take a break or perhaps you need to break off some relationship. You want everybody to know about your talents and skills. Your dream suggests people around you who are prone to violent outbursts and shifting mood swings. You are seeking advice.
If you dreamt about fish eating each other:
You can either set yourself an impossible target in the romance stakes, or you can get going on a more practical scheme to win love in a fair and honest way. Self-promotion that is aimed at making a big impact is likely to fail.
