What if you know you have a male betta fish but it is not afraid of water movement?

Hey there, i used to work in a aquarium and ill tell u that 80% of aquariums tell u to keep ur fighter in a bowl. But realisicly the are much happier in a heated tank (ive seen the proof) U can have a bit of water movement from a filter if u decide to put one in. But i wouldn't get a high powered one that's gonna blow him away. Just make sure u have some type of area where there would be less movement like a large patch of live plants or a hidey hole. Bettas come from Thailand, they are found in slow moving streams or even in shallow puddles along side the stream. Just thought i would say that :oD
