Larry, a betta ive had about half a year never flares at his own reflection. he usually just stares at himself like he knows how pretty he is!
but today i placed his tank next to my new bettas tank and they both started flaring. it was so awesome to see Larry flare. i didnt realize how big he actually is since he never flares. my new betta, Moe #2, was really beautiful to watch as well. hes young so hes quite a bit smaller but he was still really cool. he flares at his own reflection unlike Larry. i thought it was really interesting to see how they had their own "styles" of flaring too. Larry would flare and then circle his tank and return to flare again. Moe was constantly flaring and wouldnt let Larry out of his sight. i seperated their tanks again and now they are calmed down. i just thought it was really neat to watch :)
