I just found out that I indeed have two MALE bolivian rams in my thirty gallon community tank. They are doing very well, but do fight, with one of them being more submissive than the other. Should I get a female and remove one of the males?? I am worried that they will stress each other out, although they do not seem to really harm each other (someimtes funny to watch). They sure get in some lips locks once in awhile. Really looking for feedback here please.................
