Flaring Gills?

[hynesh9792]

Junior doesn't have any other mates in his tank and I seen him for his first time today flaring his gills. He did it 4 times within 5 minutes. Other than that, he's acting normal and happy. He wasn't looking at me or another object (I read that it might be them being defensive by seeing another fish or object).
My water quality is good, temp is good, etc. The ONLY thing that is weird is that he flared his gills. Is this normal?

My betta just flared for the first time a few days ago after having him for over a month. Is he new?? I wouldn't be too worried, just keep an eye on him for any other signs of sickness.

Totally normal. Good, even. He probably just saw his reflection on the sides of the tank. Mine even flares at my finger sometimes. :3

He is not new. I give him enough attention to where he is excited when I wake up and when I come home lol. He IS still a baby though (slightly, I would say teenager). Maybe he does do it and I just never see but today I was just watching him for longer than normal Thanks for the reassurance!
