What are they in your opinion? And why?

 

[Pandamania]

That's pretty easy. Gotta be Male Betta splendens, against their own kind. Even while they're mating. Also, I've TRIED keeping a 12 pack of long skirted black Tetras. They just kept picking on one another constantly, until there was only 2 left! I tried seperating them with tank dividers, and even the last two kept actually smashing themselves head-on into the screen trying to get at the other. And I couldn't put them in other tanks, they picked on every thing, including fish 2 to 3 times their own size.Even tiger barbs!
