Do male bettas build bubble nests without mating?

Yes, and it's a good thing! Males will build bubble nests when they are happy, well fed, and feel safe. Doesn't matter if there's a female around. Betas used to live by hopping from one puddle to another, so your little guy is probably hoping for a visitor...

Plakat bettas are an same as different bettas in this regard. you ought to construct a bubble nest interior an hour or so, yet even as they're truly in a breeding mood, they'll artwork on the nest for days. Dont' positioned both fish at the same time until eventually the male has built a good bubble nest, because if he hasn't, he probable isn't waiting to mate, and therefore is amazingly in all probability to injure or kill the female.

I've had two bettas in my life so far. Both were male, and both randomly made bubble nests. I think they just do that because that's their job. I don't think it's because they want to mate. You can get a female if you want, but I would only get one if you want small fishies swimming around.

Hope this helps!

My Betta does that too. There all these bubbles at the top and they stay there and he hangs out by them. He is alone too.

Hmm...I wonder why they do that! ♥~Aspen~♥
