is there much of a difference between the two? i would assume the wild to be more aggressive but is it a big difference? what about things like growth rate and apetite, are they different as well?

I have two wild red bellies and one tank raised.

The wild ones are bigger, but believe it or not, the tank raised fish is more aggressive and much less skittish. I don't know why this is, but this is what I've seen. The tank raised one likes to eat a little more, where as the wild ones seem to be fine going longer periods of time without food. As far as growth rate, they are all pretty much growing at the same rate so I can't see any difference there.

Theres a certain quality that the wild fish bring to the tank, they just kinda look badass. However, the tank raised has much better colors and better looking fins, things like that. On the other hand, the wild ones seem to handle wounds and bad water conditions better.

Overall there isnt too much of a difference, my friends can barely tell them apart and when they do its solely based on size. Hmm i hope I covered it all...
Oh yeah the wild ones have much bigger teeth.

I have had both, and the only real difference that I can associate as being "wild" is the color, and even that is only based on my observations of 2 wild reds. The f1 reds I have had and all the reds I have seen in the fish stores or anywhere else have not had the same color as my 2 wild reds. I think behavior is up to the individual fish.

Yes ,I have expirience in keeping a mixed shoal of RBP's.

There are some differences pointed out in the other post, but one thing has allways happened :

WILD P are more stable in any way .
Tank raised get earlier any desease, they don't live the same time (my Wilds reached 10 years, the raiserd died after 5-7 years)

This could be a problem of quality/quantity :

If you get a WILD P : he maybe the one that has survided
XXX of his sisters,nature is very hard...

If you raise up/breed P's professional, you want to make money, so raise up all u can get , and sell them as small as possible...

So think about this point.

But this is, in my head , the difference betwwen wild and breeded.

There is no external differences only slight varience in coloration and body shape. Only internal skeletal modifications between wild and aquario raised is a key that is pronounced via examination.

Behavior is strictly based on opinion and feed conditioning.

when talking about tank raised something you need to factor in is the level of inbreeding as well, after a few rounds of that, the rbps look pretty wierd, my bro-inlaw has one and its just odd looking (due to recessive genes becoming more prominant) look it up on the net or in your high school biology book

typically wild ones have better color but it does fade away with age so that shouldnt matter too much for you

a benefit with wild ones is a lower likely hood that you have sibling fish, that way if they do breed, chances are they arent going to inbreed

Atypical for you Nate, your not reading the entire passage and only citing the part that suits you:

Sometimes, piranhas inbreed so much that deformities can occur (as shown by the following pictures of Pygocentrus nattereri). This type of "difference" in appearance can lead to the school eliminating them. This process is called "NATURAL SELECTION." If you have a small school of piranha (more than 2), you will see how they single out certain individuals from the school based on 1) size, 2) spotting, 3) and/or lack of social behavior. According to Catharine A. Toft (University of California) an example is used of too much inbreeding of a cichlid species (Papiliochromis ramirezi) to emphasize that species lost their original brilliant coloration after many generations of captivity. There are other examples, but scientists are divided on how many problems inbreeding does cause. It is my opinion (without actual proof) that the species S. ternetzi (Steindachner 1908) might have been described from a fish similar to this one below. We will never know for sure, however it might be plausible to assert that certain populations of piranhas over generations of breeding could create a population of species with unique genetic traits passed on such as those found in the Paraguay region ie; head shape, body shape etc. But since these traits are widespread among populations of P. nattereri, it does give one a reason to think and explore if that might be the reason why some piranhas have much more unique traits than other without diminishing the scientific placement.
This also occurs in nature, hence the phrase This process is called "NATURAL SELECTION." Natural selection occurs in nature too and not limited to the aquario as you are intimating. If you note I make mention of Paraguay populations and nothing is carved in concrete, because even wild salmon vs farm-raised are difficult to tell apart other than humans clipping adipose fin. Genetically, they are the same. Other than loss of color and probably additionally serrae count your argument doesn't hold much weight or fact because you are not comprehending the paragraph I wrote into my web site.

Good to know nice topic pick by the way. I would like wild ones just because I could brag about them more, but I love my little ones just as much and they are just fine.

Wild ones are always preferable if you can afford them. But after a period of a few months (or a year or more) they look like atypical tank-raised because of the lack of suitable diet. So if you must buy wild, try and buy adult. Less likelihood of body shape varience, though the wild colors will fade over time.

i agree, this was an interesting post, and the thought if inbreeding never even occured to me before.
Now i am worried if i breed my fish that they will have weak immune systems and be half retarded

I would not concern myself to much over Sir Nathan III remarks. He is misreading my information and it would take many generations of breeding piranas before you would even see a difference. So relax.

And btw: what's wrong with owning Corky the Piranha
