How many RBP would you keep in a 240?

[DucatiDragster]

hey folks

i'm thinking of getting back into piranhas, how many rbp would be just perfect for a 240 for life? i'm thinking of getting 12, what do you think?

 

[pyromaniac]

yeah 12 will be right.can add a couple more though.
my 220gal pond holds 13 full grown reds

 

[Dulcet]

yea just kinda follow the 25 gal. per full grown method and u'll be all good.

its normally 20g's per piranhas
but for life mabey 30 gallons for life each
or mabey just about 10 piranhas

 

[razorback182]

agreed.

i'd probably throw 20 in there, that's a nice big tank

I have 18 pygos shoal 7" to 12" on my 300 gals.. terns, pirayas caribes and rbps..nice to watch when feeding live tilapia..

Yeah 240g is big, I think 10 or 12 will be good.

yeah, that's what i'd do, you could probably throw even more in there, but i'd start with 20 and see how things go. i know that everyone is suggesting the 20-30 gallons per fish rule, but with a tank that large, i think you'd be more successful in the long run with more than 10-12 as long as you keep up with the extra tank maintenance. personally, i'd use everybody else's suggestions so far for stocking a 125g.
