I'm curious about terns and pirayas. I've have caribe and reds and know they grow extremely fast. But I haven' heard too much on the grow of terns and pirayas. I had a piraya for 6 months or so and only grew about 3in during that time. What are you experiences?

All I have first hand experience with is redbllies, but they grow really fast the first months: I got mine at 1" in size, and within four months they all at least tripled in size. My biggest red, which I have since early april 2002, has reacehd about 7" in size, the 5 smaller ones, which I got in june last year, are between 4-5" in length.
I noticed that after they hit the 5"-marker (although this depends a bit on the individual fish), thet growth rate slows down rapidly...

Like I said, this is my experience with my own natts, but I guess it's about the same for the other two species. And I also like to add that growth rate also depends on external factors, like water quality, stress, diet etc., so other pygo-owners can have other experiences.

I've heard that piraya require a lot of water changes in order to reach a large size, this being said, I change my water on a regular basis, and my caribe passed up my piraya a long time ago.

In my experience I feel that Cariba and Piraya grow the fastest, as a matter of a fact nearly 1.5 times as fast as a common red belly. Ternetzi grow faster than reds also but not as fast as the other two.

Cariba and Piraya in home aquariums with excellent care takers can grow at 2" per month until they reach maturity

hmm

most pygos grow to 6" after 6 months.after that they grow like an inch a year.

When I have my caribe and piraya together, they started both at the same length. Then the caribe just started growing crazy. Even my friends piraya is alot smaller than his caribe and the piraya was 1.5 bigger to begin with. Now his caribe is 10" and the piraya is about 7in or so. I'll be getting some pirayas but I don't them to such a slow grower.
