So, I got a juvenile betta fish a few weeks ago, and I have two adults already. The cup I got it in said it was a boy, so I assumed it was. However, my two adult male betta fish have blown bubble nests, while this one has not. Instead, my juvenile has to long black stripes. I'm sure it's not anxious, as it shows no other signs of that. I think it might be a girl, and those are breeding stripes. It would correlat with the bubble nests, and I've heard stories of petco mislabling the betta fish before. What do you guys think? Pic is fish, sorry for the quality.

generally speaking, it's females that develop stripes and that LOOKS like a female BUT the stripes being displayed there are 'stress stripes' bot breeding stripes. Stress is horizontal, breeding is vertical. Males can show stress stripes if they're light enough. Also both males and females blow bubblenests, males are just a lot more likely to do it

look at your juvies underside. If you see a white spot, you've got a girl. Look up 'egg spot'
