I tried. Everyone advised me to stop and get one of them out of there. My ocellaris was clearly showing dominance over the maroon and gave him daily beatings but my maroon wasnt mature then and had no reason to fight back. I eventually got rid of the ocellaris after I added a yellow watchman goby, royal gramma, and a purple firefish which the ocellaris then decided those 3 fish did not deserve to live. GOOD LUCK!
