Sorry, I know I am a bit late. New to the site.
But I agree with others. You should be fine. I have kept 3 in a 57g and they never even looked at eachother. It was great. If you are worried about running low on copepods order them from REEF SCIENCE on ebay. I was recommened to them and I got 3 or 4 bags a few months ago, and dumped them in my fuge. Now my tank is crawling with pods. if I pick up andthing at least 10 scurry off.
I would still continue to feed them tho, don't jsut rely on copepods. My ornate its anthing frozen and pellets. My other leopards did to. (lost them in a move). I am looking to get a blue star and potters again.
IMHO the most important thing in keeping leopards is a tight lid. When spooked they jump. I am always getting my ornate out of my overflow.
Nice pic, just keep an eye on it and you should be fine.
