More Corys in general would make all 3 more comfortable. It's suggested to keep each species in sets of at least 4, so more Julii would be good too. It depends on the space you have to accommodate them. I've found that most Corys will hang out regardless of species. Even in the wild Corys intermingle. In my tank I have Pygmys that chill with a large Melini, Pandas and Sterbai.
