What, no piraya? Just kidding lol (cariba's are my favorite anyway). I bet they're dinner plate size in that 700g. You ever get into Serrasalmus sp like manueli, elongatus, or any of the rhombeus locales?

Have you noticed the different species segregate at all or have any issues with being mixed? I'm guessing they are such similar species they all school interchangeably but would be interesting if you observed otherwise.

They'll school but expect cannibalism.. same species or mixed. At least from what I've seen in documentaries.

As long as they're well fed and you have at least three to disperse aggression, then it's a pretty rare occurrence in captivity. You might get a few nipped or torn fins occasionally, but they'll heal.

There's been plenty of discussion around cannibalism and being well fed and there does not seem to be a correlation, at least from what I've seen/read. You might have of course personal experience that says otherwise.
Of course they'll heal if nipped, they are nature's wolverines.

I have a little bit lol. Cannibalism is usually a by product of aggression, whether territorial or breeding. One fish gets picked on too much and gets killed. If the fish are well fed, then you'll usually be pulling out a corpse as opposed to skeletal remains. By keeping at least three in a school, you have better odds of dispersing that aggression instead of having it focused on just one specimen.

Nothing like a well fed shoal with plenty of hides only to wake up to a head or two floating around. Sometimes I think they're just assholes... like people... you know... start <edit> and well, who knows where it goes

And hear I thought wolverines were nature's wolverines

Neat, so mixing pygos of the same size is usually no problem it sounds like.

Correct, they're all schooling species of characin. Pretty much just a big tetra with teeth. Now Serrasalmus sp., those are an entirely different story lol (except S. geryi, some people have had a bit of success with them).
