We are new to aquariums and bought our son a male female pair of swordtails. They've only been in the tank a few days but the female has become extremely aggressive towards the male and chases him around the tank, biting him as she goes. She seems to be territorial and won't let him near the front of the tank. When we put food into the tank she chases him away and won't let him eat. Is there anything we can do? She's a real bully! I'm worried he's going to starve!

Depending on the female Swordtail's size to the male's,I've seen exactly the sort of behavior you're describing..depending on the size of your tank you could try doing what I did,which is adding two other female Swordtails..a female to male ratio of three to one in most species of Live-Bearers makes for a happy male and three less stressed out females..worked for me,might work for you.
