I had bee trying this but had a tank crash that took them all out. Had them all in a 75, 4 juvi skunks and 4 juvi ocy's plus a spawning pair of skunks. Started with just the juvi's for 3 months, they all hung out and I was prepared to separate them as needed. The spawning pair was not supposed to be in there, couldnt pass them up and needed to cycle a tank so I threw them in a breeder box that they jumped out of. They were playing nice with the others so I decided to just keep an eye on them and put in an egg crate divider for the juvi's to escape if needed. Tank crashed a month later so that ended my experiment.
If I do it again I plan to get a large pair of skunks and a small ocy male (or maybe reversed), dividing the tank with eggcrate so the extra male can escape. From my research the issue with creating a skunk ocy pair is they have different behaviors or "language" and cant understand each other. Also its been said that perhaps its a male of one species or the other suddenly swimming in and fertilizing the eggs during spawning, which is seen in some other species. So my hope with this type of set up would be that during a spawning event the extra male would rush in and take a shot at fertilizing the nest.
