my black convict cichlid pair got into a fight with my jag and the jag swallowed the female chewed her up then spit her back out.the convict was missing almost all of its scales its left eye and its fins.it even died with its mouth open and the jag cut into the convict with its teeth and the cons guts were hanging out of its sides.then the male comes over and takes a little bite out of her so i took the male convict and put him in his own 30g tank with a 6" goldfish and a new female.i put the jag with a male RD and a female JD in a 100g tank.
