is 90 gallon with 5 4-5" P's too small for them to fit comfortably?

i have a 90 gal, i just got rid of 4 P's and i want to know if i should get rid of more, my goal is to breed them.

I think that is a sufficient tank size. I am not sure if it is enough for breeding them though. I have no experience with breeding so I am not sure if they need more room for that.

5 piranha will be happy in a 90 gallon tank, but as for mating I am not sure. I have read that you need a lot more gallons per fish and cleaner water, but I have also read some posts from people who said that they had none of these 'favorable' conditions and their reds mated. Give it a shot, you never know.

Reds will start not spawning until they feel comfortable about their surroundings, and you're the one to achieve that for your fish.
Once they start showing breeding behaviour (ie. pairing off, starting to build a nest, agressive territorial behaviour, darkening of coloration), you could take them out, and put them in a tank of their own (I guess 50 gallons will be suffcient, because they can do whatever they want without being interrupted). There's a very real chance they'll continue with their breeding behaviour quickly after they've been moved.
Once you feel like you have enough fry (made enough money
), you could place them back with the others, and just let them be...

I have heard in the past that people have breed reds in a tank as small as a 55 gallon, although I would suggest a lot larger tank such as a 125. For your fish a 90 gallon is gonna be good for a long time.
