Just not male male. What about female female? Just out of curiosity. I am finding mixed information on the subject.
Not really they don't do well together long term at all from what I understand. If you get a bigger tank you could do a couple snails, my betta does fine with cory cats( but at least a 10 gallon would be best). Or you could do dwarf frogs, but keep an eye on them to make sure they are getting enough food.
