I have 1 male aratus cichlid and one female. I've had him bout a year now. Just decided to get him some company. But soon as I put her in he chased her down attacking her. Now she has no tail fin and can swim anywhere she just basically floats up and down in the tank. I know he's trying to show his dominance over her, but will he go too far and kill her? Should I put her in a protective lil net box that I have?
