I'll be setting up a sorority soon and I was wondering if Bolivian rams and bettas would get along. If so, what pair would be best: male x male, female x female, male x female?
That sounds fine to me, more females the better, they will be aggressive for the first week or so but should soon settle down, every time a new female is added this may happen though!
Guppies can be an issue because of their bright tails they can be nipped at and bullied by females [happened in my case anyways]
