Airstones and bubble walls cause lots of surface agitation, but not a lot of flow in the tank. And just because a fish has a labyrinth organ, it doesn’t mean it wants low oxygen water.
If I were you, I would research what a healthy betta looks like. Lemme copy and paste the list I check when looking for one:Is there some sort of way to judge the personality of a betta before getting it?
TBH, it really depends on the betta, but I would assume that most like it as from what I have heard and experienced, they are pretty goofy fish who like to frolic around their tank.
I disagree. A bubble wall or air stone will not create very much of a current as all they do is push air into the tank. They do not suck anything in or push anything out. Just because bettas have a labyrinth organ does not mean that it is their preferred method of oxygen intake. They would much rather take oxygen in through their gills rather than go to the surface to breath air. I know that in many cases, a air stone/bubble wall is used to oxygenate the water, but in this case it will do that and it could potentially give the betta a place to play in.
