I don't know if it's just me or what but I've never heard of a betta being in a tank that holds more then 10 gallons. I was wondering why? I normally see them in 1-2 gallon tanks sometimes smaller. Couldn't you keep more in a tank if the tank was bigger?
 
bettas, male and female, will absolutely take all the room you can give them. i have kept both in a 50g tank, but only one at a time. males will most likely fight each other no matter what, unless they are siblings that have been raised together. even that is up to chance. you can keep females together with few problems, but at least 3 or more - they are not as aggressive as males, but can be territorial and will develop a pecking order. heavy planting/broken sight lines go far in reducing squabbles.
 
I wonder how they would look like in my 55g. maybe 10 of them
 
lol well thered only be 1 after a few hours.
but back in the community happy tank days i had one in a bowl, moved it to the 55, it wouldnt stop swimming. Also thier typically not kept in bigger tanks, bc most fish with it may nip its fins, and bettas are more prone to fin rot/fungus then others, which will kill the fish if this happens. Also bettas are not typically strong swimmers, and even the current of the filter can stress and wear them out. The fact that thier part of the Belontiidae family means they can breathe air and survive low oxygen environments, which is another reason why thier commonly found in bowls.
 
they'll be fine in larger tanks if you stock it appropriately. but like someone said, being frilly as they are, they are not the best swimmers and larger tanks usually will have higher currents. however, they are not more prone to fin rot or fungus, and will not definitely kill the fish.
i keep a betta in a 10 gal with lots of plants to break up the current and it's healthy and gorgeous. it may be upgraded to a 20 gal long once i start selling off a bunch of my smaller tanks, i don't think current is a big problem in a long tank if the filter is at one end.
 
I have been told that bettas, even males, can co-exist as long the alpha male is still alive and not removed from the group and that there are no new additions; otherwise a pecking order will start again. If I am not mistaken, a couple of people on this forum confirmed this as well.
 
well mine got some form of fin fungus after its fins got nipped and even though the water was clean it died. The other one i had, fins got nipped, somehow he didnt care, and lived for years in the 55 untill just recently due to old age. I guess the cases just vary per fish... That would be cool to see a tank of all male bettas.
 
I read someone kept male bettas together in a heavily planted 55 gal tank. Would like to hear from those who keep males together on here.
 
I have had a male in a 10gl for sometime and he even shared it with a bullhead baby for awhile with out issue. He loves his 10gl tank No swimming issues at all, he goes all over.

I had one in a bowl I just for the heck of it tossed him into my 55gl. He is happy as can be in there. He flares up at the tetra at times and will chase them away, but the tetra leave him alone and dont nip.

My rainbow shark on the other hand, picks on the betta the most :( Shark is moving soon.

The betta stays at the top in the corners and finds his spots the current isnt as bad to rest and uses the entire tank on the top to swim.

I worried a lot at first, he seemed to struggle so bad in there. I realized going from a bowl to a large tank with moving water would take some getting use to and he does great. Doesnt seem to struggle with the current like he did at first.
