I Have A Black Molly Thats Been Very Agressive-could It Be

[sycko]

that shes pregnant?
i bought a couple of mollys a few days ago! white and black! anyway yesterday i was cleaning around and noticed i have fry in the tank! little white and black ones realt tiny! so i scoop them up and put them in my floating tank! anywayz i have noticed the black molly is attacking every fish thats swims near it! well the white molly and my plattys anyway!!
so i was wondering if she is still giving birth and is trying to protect her young? but she has been like it since we bought then 3 days ago!
any ideas?

Is she a male or female? She may be confusing the other fish for female mollies if it's a male.
It's possible that she is giving birth and doesn't want anyone to come near her... but might not be since you say it's 3 days she's doing this...
