A Pygocentrus piraya is one of three types of pygos that is considered the most aggressive. They have a very profound lower jaw and have flame type markings that extend from their belly up their sides. That is quite a stocked 90 gallon tank, you might consider moving them to something equal or greater than a 125g. Some purists will tell you 180gallon minimum. Welcome to the site noob.

So you're just going to let them kill each other and however many you end up with is the magic number? If you want...tell me where you live and I'll take the ones you don't want off your hands so it doesn't have to come to that.

No iwant them to fight, the strongest survive, i'll have crazy piranhas!!!!!!!!! i have redbellies.
i mean i could give them away but i'd reather watch them, plus when they die since they are made out of bone and muscle i want their skeleton for the bottome of the tank.

Yes I understand that you want "aggresive fish" but encouraging animal cruelty and not to mention a waste of money is not the best of solutions. May I suggest a different solution. I am sure there are plenty of members here that would be willing to take them off of your hands and maybe even give you some $ as well.

I'm in agreement with Python...he's definitely stirring up some shyt. Plus thats a lot of money down the drain for buying and raising and feeding piranha's just to try and get one to kill the other.

Yeah.. extra $$$ to buy other and different varieties of other things to see your RBs get aggressive on.

Oh yeah, if the others kill some of your piranha's...the bones will not be left more than likely. So if you want to keep the bones you're gonna have to complete the murder yourself. Which I also don't recommend. They're your fish of course...but come on...its the murder of a piranha or many. I'm not one to talk though...when I first came on here I tried to get my rhom to fight an oscar...which I thought twice about and pulled him out and now he's fine. Seen the error in my ways and was flamed extremely bad for it. Anyway...let the p's live.

that dosnt make them great fish, just meens they need space, and why waste so much money on such rare fish? In a tank that small, two will end up, but then, one will kill the other, and you will end with one, WOW way to go loser.

I think this guy is just a newbie. Your red bellys are considered the "least aggressive" fish in the home aquarium. I bet they wont even fight. Their growth will just be stumped.

As to your original question about sexing piranhas, please refer to our science forums as this topic has been covered in great length. Short and sweet answer: You cant do it.
