Hi, i have 5 black mollies in a 25g, along with some platies. I recently been keeping a close eye on them over the past 2-3 weeks, and one black molly is chasing the anther around with its fins all the way up as if it is excited. The molly which is chasing the other one is much smaller than it aswell, is it possible that they are showing interest in each other to breed or whatever? And what do i do if they are? I dont have another tank.
Any help info, advice info etcc. very much appreciated
A molly male that is swimming next to another molly and displaying its fins fully is a happy, healthy, horny male. If it has been doing this for any time at all, it has probably bred with the females in the tank. That will not be a problem for you unless you try to save the fry. The mollies often do not eat their own fry but the platies will take care of population control. You may have a few accidental survivors but not many. In my 120 gallon tank, a platy gave birth to one after another drop of fry and I have exactly one survivor to show for it. In the same tank, my female molly gave birth to several fry drops and there were no survivors. When I moved her to a small birth tank where there were no other predators, this was the result. The picture was taken 35 days after the molly gave birth to those fry. At the time she was huge with her next drop.
