Mollys being Aggresive

[trijjj]

I have 5 Mollys in my tank two of wich are males, These two males chase and pick at the three remaining female mollys. A forth female Molly was killed by the two. Any suggestions as for calming the two down. I would hate to get rid of them as they are great looking fish. Also when I first got the two male mollys I had no issues with them, they were very active in the tank but did not bother the females.

Livebearers like mollies generally do best with a 1 male to 3 or more females. The three females are being harrassed by the two males. I would suggest exchanging one male for another female, or added several more females.

What sized tank do you have them in? Is the tank cycled?

They are in a 75 gal tank and the tank has been though its cycle a few months ago. All analyzed levels are very good.
I will try to trade one of the males for a female.

Are there a lot of plants or hiding places in the tank?
That might ease the aggression.

I would agree with OC. Any time I've had more than one male livebearer in with multiple females, it's been nothing but trouble. Either go with all males, all females, or one male with multiple females.
