I have a 36 gallon bow front tank that is currently home to a female Kribensis and other peaceful schooling fish. My question is: can I add a Bolivian Ram pair to my tank? I know having a pair of Kribs and a pair of Rams in my tank would bring a nightmare, but what about the single Kribensis? Will she be aggressive towards the pair? Should I just add a single ram? I have many questions and answers would greatly be appreciated. Thank you in advance.
