I currently have a 120 gallon tank that houses 2 oscars, a pleco and a shovelnose catfish, I want to start a pirahna tank and I am going to, once the fish in the 120 are gone. The question is: How many pirahnas can I fit in there?

people say to go with a p for every 20 gallons..

 

[Piranha King]

what are the dimensions? if its 6' long and at least 18" wide go with 8-10 adults. or more babies if you want to see how a huge pack does and maybe sell some if you need to.

Most Piranha buffs will tell you 20 Ps per gallon. But in my opinion, anything larger than 80 gal can hold 2-3 more. Im 2 Ps over the rule with my 125 gal, and everythings perfect!!

I thought the dims. for a 120-5 is 13" depth? Thats ultimately why I ended up getting the 180 is the the greater depth.

 

[deeboi]

actually a 125 show is 72x18x20. I know my 125 that I had wasn't a narrow 13" depth.

My bad, I just remember looking at getting a 125 and thought there was a bigger difference other than 55 gallons.

Okay thank you everyone. Another question: what would be some good tank mates with them?

What would happen if you are cleaning the tank? Wont they attack you hand?

"I would recommend only keeping 2 piranhas per 60gallon tank (depending on species), and at least 20gallons extra for each additional fish. It is possible to add more fish, but if you want your piranhas to live happy and show natural behavior, this is the best formula, in my experience."

the piranhas will not attack your hand they are just as scared of your hand as you are to them so dont worry but just dont chase them around with your hand they could bite it out of defending them selfs

BTW in a 60 gal tank you could have 3 in there with no problems and will still show natual behavior also the 20gal per p is only up to 85 gal after that it depends on the tank
