I just started an african cichlid aqaurium. I have a baby electric yellow, princess cichlid and another baby fish that has a yellow bottomhalf but a black andd white striped top. I also a have a femal lombardoi that is a lot larger then them. They are all babies. The three litllest ones are always at the top near the filters and heater, because they are being bullied. HOW CAN I FIX THIS. Maybe put another aggresive fish in so she isnt as dominant?
