I went to my lfs today to buy some platies, which they didn't have. So I got two dalmation mollies instead. I did all the research on platies but not mollies so I have a few questions. How do i tell the males and females apart? I think I have at least one female because the guy at the lfs said one was pregnant but I'm still not sure. Is 78 degrees F a good temperature for them because I'm getting conflicting reports? And I know that livebearers are suppose to get along well with each other but i have one male swordtail who lived all alone in the tank for a month. I'm scared he'll be territorial. Oh and do sword and mollies breed ? Thanks
