How high can bettas jump?

[Option]

I hear all these (horror) stories about bettas jumping to their deaths. Personally, I have never had any of my bettas jump. But my present sorority tank is in a rimless tank and I'm wondering how low I should keep the water in order to prevent any suicide jumps.

2-3 inches from the rimtop okay for the water level?

Lids are better because of the humidity they trap. But I would lower it 5 inches and cover the surface in floating plants.

I would think 2-3 inches would be enough.

Edit: rimless tanks looks amazing! If your really worried, you can get white craft mesh and make your own lid or get some plexiglass that can keep the rimless look. (:

Floating plants.

I think like anything else it depends on the Betta & how close to the side the Betta is. My girls go crazy jumping up & over each other when its dinner time but so far nobody has gotten any real air. I would put some kind of light weight cover on it to just be safe.

I have 2 open top tanks and two with tops. Overall I prefer open top as they look better. I have never had a fish actually jump the tank and the glass on one of them only reaches a few Cm above the water line, the other alot above.
I used to have a jumping plakat that jumped his seperator.

I think 2-3 inches are fine.

About 3 inches should be plenty enough to prevent them from jumping out. Mine used to jump until they got older.. one still does, she'll jump into your hand if you lower it enough, as well as jump out for food. Don't need floating plants.. if they want to jump they will find any opening and do so.

I have had mine jump 5" high (one did who holds the record in my house for the last two years) and 10" across however that was for food and not much else for reasons. 2-3 inches is fine, and recommended especially for those happy jumpers. :)

That's insane.

They were insane every jump they made I measured... Average jump was 2.5-3 inches, record 5
