Betta in really big tank?

I don't have a big tank anymore, so this is just for curiosity sake. Anyone have experience in having more than one male in a really big tank like 125g+ ? Traditionally Bettas are kept in small tanks, I have one male in a 20g community tank with 2 SAE, 4 Cory, 3 Otto, a few platies. The male tries couple of times a week to pick on some platy but never got into any fights, more like platy just turn and bye. I won't put another betta, male or female, in my 20g. But am curious if it could be done in a densely planted big tank?

 

I've heard of offspring of a male living without him in a heavily planted tank with no issues until they all peacefully passed away. My friend kept the male's daughter and son in the same tank with him. I believe it was a 75 gallon

You know, most bettas are kept in small tanks, and we all know that bettas are very territorial. But there's no information online as how big a territory do betta males need to feel enough space. I suspect heavily planted may be a must so all betta could claim a corner as his won and they don't have to see each other. We have more information on cichlid than betta when it comes to space needed.

So in the wild, male bettas will have about three feet of territory, but that's about all I know when it comes to that.

Yeah that was part of it, though the bettas were seen interacting a lot. The dad actually was more snappy toward the daughter than the son surprisingly! They made sure to keep the fish separated during feeding, but it was overall very successful

 

I've bred Bettas in the past, as long as they don't have eye contact and the owners don't change things around, then males are fine together. What happens every now and again is they see each other and flare up but they soon go back to their corners. What we humans do is play in their environment and change things about, that is what causes the issues.

 

It could work in a very large tank but you'd probably be safer just doing related females but agree with the above that I've heard of males that are siblings living together.

 

I have commented before about the survival of a species over the survival of an individual. A species member wants to be the strongest, but doesn't want to kill the other member, as if it dies there is no one to take its place, and that is counterproductive.

Good point
