Why not? Lol, its not a dumb question. They are not really classified as a schooling fish, they will do ok by themselves, but some consider them to be a schooling fish. My personal preference for any small fish is to have a couple of the same species together. For example in my fiances tank, she has four dalmatian mollies and six sunset platies. She also has about 8 corydoras. She COULD have one molly, one platy, and 8 cories (corydoras are schooling fish), but they all like to interact with each other. I hope I didn't confuse you instead of helping you.
