I had a sixline he eventually jumped out after almost a year think My green coris chased him out though I never seen him eat bristles or any pest but he was always in the hunt for something the green coris wrasse was a good pest eater ate bristles and flatworms but the sand storm he caused multiple times a day lead to him finding another home. Had a file fish who ate aptasia pretty good but when it was all gone started eating zoas so he also had to go my fav animal is my harlequin shrimp he decimated asterina stars but now that they are gone have to feed her chocolate chip stars but I love watching her wrestle the star when I first put one in its like they can immediately smell it when it hits the water she comes out hunting for it almost as soon as it hits the bottom
