Put a couple big male long ears in the tank. A group or 4 or 5 males seems to work best. The females get beat to crap and they pretty much killed every other fish except my black crappie. She runs the roost. Only got decent phone shots of one but they are identical. Of the 5 I raised from last years yoy, 4 are left. Like I said the females and sub males are beat to crap. The dominate male got his but kicked by the new guys. Took a chunk of his ear. He used to pick on everyone and now he just hides.
