Growth rate is about 3-4" 1st year and 1" or so after that. With optimal water quality and nutrition, will take 10 yrs.

Actually, You can grow them much more than that in a year. In great conditions, they can easily be grown to 7-8" in the first year, with 1-2" a year growth thereafter. I have a breeding pair that is a year and a half old and are a little over the 9" mark. Terns, cariba, and piraya grow much faster than reds. I had a tern grow 3" in 2.5 months.

Wrong
... Pygocentrus nattereri can get over 8" the first year with proper conditions... then they continue growing at a slower pace ... keep in mind growth depends on many many factors: genes (the individual), water conditions (filtration + water changes, no nitrates, enough oxigen), feeding (varied diet, enough food), exercise (tank current), water temp (related to fish metabolism), tank space (related to water quality), general health (no illness, parasites, stress...)…

Piranhas are bony fishes and bony fishes never stop growing. So who knows how big a Piranha with the proper care can get.

If you don't beleive they never stop growing, ask Frank at opefe forum.

Yes this is correct info.

Of course, on the other hand, you can say a fish is full grown as the phase of rapid or even moderate growth is passed.
Then I would estimate, that in good care, Reds go on growing 5-8 years and reach the length of 11-12 inches or even more in optiimal environment. Still as been said they keep on growing after this too, though much slowlier.

I agree. What scares me is that with all the information we have on Piranhas now this day, who knows how big we can grow them.

I have had my Tern(red variation according to scientist) at over 10" in less then a year and no I don't overfeed. My pygos get fed every 3 days.

RB_32 has his at over 13-14" already(although abese) and he has had his less then 2 years, so who knows how big he would get them.

I wouldn't be surprise if in a couple of years, we see reds at or over 20".
