I was reading the facts sheet on this forum and from what i got out of it, red bellies, pirya, and caribe are the only piranhas that school together right?

so from what i *think*:

1) piryas- are the meanest schoolers
2) caribe is next
3) finally the common pet store red bellies

Am I right? If so who sells baby (dime or quarter size) pirayas and caribe and how much are they? How hard is it when it comes to resell? lets say i move or somethign, will it be easy or hard to get rid of pirayas and caribe? thanks, any and all info appreciated

I think what your wondering is if the pygos (natts, piraya,caribe) shoal together at the home aquaria then yes you are correct. In the wild however there are many different types that shoal and are hard to reproduce in the home because we don't own 1000+ gallon aquariums. So yes reds, piraya, and caribe shoal together also you cant generalize on which is more aggressive than other it really depends on the fish itself and its aggressivness. Out of the peopleon the boards and by my little experience with the piraya I have i would say yes they are aggressive but then again thats just a opinion from me.

You most likely will not be able to find piraya or caribe dime sized usually 2-3 inches is the smallest and even that is hard to come buy. There is great guy on here he name is "fishpost" he will hook you up with what you need. Piraya tend to be the most expensive because of there rarity, then ternetzi ( a different coloration of a redbelly), and then caribes. And ofcourse reds being the cheapest because they have been breed tons of times in home aquarium, pet stores, etc...

As far as i know a Cariba shoal is the most fearsome in the wild (use to be 30 or more of them together) or in captivity (most territorial).

As individual i agree Piraya is the meanest but if whe are talking about many Ps, i think Cariba get the award!

I agree, Caribe are by far more aggressive in shoal. I had 15 and they tore anything up in the tank and not to mention they ate alot more than other pygos I had.

Are we talking about only Pygos here? If so then you all have good points. If not, then...

A spilo school is pretty cool too. I have 10 in my 180 and they are pretty aggressive. Now I dont want to speculate they are more aggressive then caribe or piraya, because frankly, I have never "personally" witnessed either group. However I do know that they are definately not skiddish, more more more aggressive then my reds i used to have, and alway hungry.

Perhaps if someone lives in the LA area you can come over and take a look. I think that you guys are underestimating the sheer aggression on a spilo tank.

I was speaking with Frank this weekend and he brought up an interesting point of a schoal of piranha's in the wild can often be mixed between different pygos and even serrasalmus. He told me that often times you can find them schoaling together in the wild. I believe its because serrasalmus are not necessarily more aggressive than pygos except when kept in a limited area. When they're in the wild they have much more wide open spaces to claim territory and with an aquarium the space is much more cramped and the territory claimed often by a serra is even too small and anything that invades its cramped territory is viewed as a threat to its kingdom. Feel free to add anything to this or tell me where there may be a flaw.

I saw a photo similar to that myself. I'll leave it to that person to read this thread and maybe post a pic of it cause they should know who they are. But it was a rather large tank and I picked out a few nattereri but what really caught my eye were 2 much larger silverish piranhas that I was unsure of what they were...I didn't think they were any pygo as the pygos like Caribe, Nattereri, and Piraya are not that grey/silver if even at all. I instantly thought they must be a serrasalmus class. I didn't see any black stripe down the face so I ruled out Geyri which are also another shoaling Serra as well as Spilopluera. My only guesses were either Rhombeus or Altuvei. I'll see if I can PM the person to give me the pic or have them post it in this thread to see what you all think

That tank that you are refering to was quickly taken over by the rhoms. There are a few pics of it when it was first set up, but I was told that after 3months the big rhoms had already killed many of the big pygos.

No one even mention ternetzis. I am disappointed. I know they are related to reds but come on if any of you ever have owned them they do not act like reds. One minute they are calm the next they are flipping out and going balistic in the tank. Ask "meanfish" predatoryfish.net how aggressive ternetzis are. I know he was trying to put together a ternetzi tank but they started to kill each other off so he quit. I wonder what ever happen to his fish.

Caribe are still amazing!

Here are the pics. Its a 500 gallon tank. This is definately by far the best school picture that I have ever see, PERIOD!!! You can clearly see that there are a few rhoms in with these pygos:

Again I want to stress that this tank did not last long. It was a matter of a few months before the rhoms had killed alot of the big pygos. This ultimately led to the owner removing them.
