I think both, John and Dave, are in part correct. Most Corys will compete with Apistos for the same resources. Having said that, the dwarf Corys (at least pygmaeus and hastatus) might be exception. These two species (can't remember about habrosus) prefer to stay in midwater, thus not competing with Apistos as much as your more "typical" Cory. I haven't kept them together but I can see how one can breed Apistos with dwarf Corys. Now, question to John. Have you been succesful breeding the dwarf Corys with Apistos?
