How come the betta fish from these pictures is not drinking the other fishes?

It is a dream fish home.

I wonder how this betta is aparently so calm and not attacking between these fishes.

If you look at the other pictures you can see that they are dwarf gouramis, not bettas. I can only see one betta (the blue one), and as everyone else has said, a betta is mostly only aggressive towards other bettas.
Sometimes the bettas will get along with other species of fish, its just other bettas they will row with. I've kept betta fish with platties, mollies and swordtails before next to no problems, as long as your tank is big enough, but its usually advise to keep the betta with no other fish because sometimes there are problems keeping them beside other fish such as fin nipping. But usually its the other fish in the reservoir that will be harassing the betta because of its long fins.
Yes, they usually can live with those fish, they do go and get along with gourami's and such.

The aquarium is real, and the picture is real.. You can take it here:

Because people seem to be grossly misinformed about betta behavior. They are not horribly aggressive fish. They are somewhat territorial but single to their own kind. They do sometimes feel threatened by other fish with similar features (i.e. long flowing fins and similar colors). I own kept male bettas with many other community fish near no problems at all. I've even kept a male betta with females near no problems. People are given wrong information, take it for truth and spread it around, without bothering to do any real research on the concern. Bettas are relatively peaceful fish.

While Betta fish are known to attack other fish, it's not like they're blood-thirsty fiends whose singular mission in life is killing adjectives other moving objects around. It's like seeing pictures of humans posing next to lions. They may be docile in that one situation, but you still shouldn't approach one lower than uncontrolled conditions.
Contrary to the popular belief, bettas actually can get along next to other fish. Females can get along with other females (only if they form a group of three or more) and males, although they cannot carry along with any other bettas, male or female, can procure along with non aggressive community fish that do not resemble bettas (long flashy fins).
That thing is so awesome!

I'm definately getting it!
you could keep male bettas with other fish, as long as in that are not more than 1 male , and that the other fish arent aggressive, since they will tend to nip at the fins
MAYBE THE TYPE OF FISH GET ALONG
It depends, Maybe the fishes are suitable for combat fish?
Answers:    Most bettas are not aggressive with adjectives fish.

Bettas only attack other bettas or fish that resembles themselves (gouramis). That's not even a real pic.
