i got mine around 3 inches about a year and a half ago or so and hes already 6 inches or so hes huge...in my opinion it depends on how much u feed them cuz now with two other rbp that are smaller they easily can eat 15 to 20 feeders a night wen their hungry

Depends on how you define "full size".

If you mean adult size (so around 12), 6 years could be a reasonable estimate, but it depends on many factors (diet, genes, water quality, stress levels, overall health, etc.)

If you mean full size as in full size, the answer is never - if they have enough space, fish continue to grow during their entire life. It might take 5 years to grow an inch once the fish has reached a monster-size, but under the rigt conditions, the process doesn't stop.

ive found that in warmer water they grow faster as it increases there metabolism

all i have is red bellies n ive found they grow 1/2" per month untill 5 or 5.5-6" in length n then slow down to a bout 1" per year after

but i keep my piranhas in slightly cooler water

my lone red doesnt eat much at all but my shoal of 6 reds at 2-3.5" take down 15-20 feeders every other night
but theres 6 of them
