Ok quick question now.

This is the second time my mollies have had fry. The first time that it happened I was not prepared for it so most of them ended up dying unfortunatly I had five of them survive. Although now my mollie has had a second batch and I now have fourteen fry. I was just wondering though why are all of them female. I didnt get one male fry for some reason. Does anybody have any information for me about this?

I *think* it may have something to do with temperature, or I may be confusing fish with herps.

What is the temperature in the tank? That is most likely a complete guess, though.

Many, many, many, many, many studies have been done to explain the phenomenon. Some have said water chemistry, others temperature, while even others have identified the amount of light. Sometimes I think that nobody really knows.

Oh, than my theory is out. I was thinking like if it was at 73/74F or so, then it would work.

But I have no idea now.

Most likely near equal numbers once the fry have had a chance to develop. The molly is one of many typical livebearers where all fry look like females for the first couple of months.
