*Intrupts* Yes you can keep all those fish together (= I don't know if breeding on accident is a risk (wouldn't be NEARLY as aggressive though if it did happen because the male could choose the female and there'd be plenty of space to get away) (Also, I don't believe the member with the 125g ever had breeding problems)
Also, yes multiple males WILL fight. But only on the level of sorority girls, since Bettas tend to fight until they give up and they only get seriously injured in tiny tanks with no cover. And I believe males give up after a couple of nips willingly in large tanks, just kind of establishing territories and pecking order.
Also, 100 gallons is not too much pressure. In some places in rice paddies the water is multple feet deep, and they stay on the bottom there. The 10-20 foot zone seems more reasonable for too much pressure.
You should go for the mega community/sorority/male combo!! Awesomest (real word? lol) tank on Bettafish!
If guppies are jewels, than Bettas must be rainbows
