Apporoximate growth rate for rhom?

[darkmatter]

How fast should my black piranha grow in a 4ft long 90 gallon tank if kept under good conditions? Right now it is probably 3 inches. So if i feed it everyday and take care of the tank how fast will it grow?

1"-2" max a year, slow as hell

it also slows down with age...half an inch a year once aprox 12 inches is attained...

yeah...
I got my at 10 inches in 2002. I think he's right at but not over 12" now. He was in a 75 half the time span. Now in a 125.

it should hit around 7-8" in a year, then it will slow to half a inch or less a year.

Damn, they grow so slow, I never knew. Especially compared to some fish like oscars that can reach almost a foot in a year.
