Hello, I've owned an aquarium for about a month and a half, and I just recently introduced 1 sunburst female, 1 sunburst male, and 2 female red wag platies. I also have a betta. Recently, it has become obviouse that the male has made the sunburst female pregnant. Currently the male follows the female wherever it goes, and if the other platies get near the female, it will chase them through out the tank. Ironically, our male betta isn't aggressive at all anymore, and isn't bothered by any of the fish. Anyways, as of yesterday, the male platy took a bite out of one of the red wag female's tails. Since then, it has become very shy and tries to hide from all the other fish.

My question is, will the aggressiveness of the male die down after the female has it's first set of fry? If not, how can I make it become less aggressive, or will I just have to separate if from the other fish. I currently do not have another tank, and would hate to kill the fish, but I may be able to give it to a friend. However, I would prefer to avoid this, even though I do not exactly want my tank to become filled with baby platies.

Thanks.
 
Doubt it'll stop. Do they have plenty of hiding space?
 
Tank size?
 
20 gallon tank, and yes, I have quite a bit of hiding places. It seems to only hide now.
 
Get more females to divide his attentions. You can mix and match any color or shape of female Swordtail, Platy or Variatus if you don't care about making mutts out of mutts. The parents will eat their own as readily as their tankmates, so I doubt the tank will become overpopulated, but a few may well survive.
 
Something just struck me. Water temperature?
 
78 degrees. The poor female has another bite out it's tail. I may just 'dispose' of the male.
 
He's certainly a randy one! If you can get the tank a few degrees cooler it might settle him down a bit, but you don't want to go under 72 - 74, so there's not a lot of room to work with in that regard.
