I bought my second betta fish yesterday and put him in a 1 gallon tank next to my older fishes tank. Whenever he catches a glimpse of his reflection he will continuously stare and flare his beard. Sometimes when he's in the middle he will swim right on over to the side bopping him in the mouth. It doesn't damage him but I'm concerned. Sometimes he will look through his tank at my other fish when they are at the same level. He will show his beard (I think it's called flaring but I forgot sorry
). I've read that this can cause stress (reflection) and was wondering what I could do to prevent it. I recently lost a fish do to fin rot and am very paranoid and check in on them frequently (5-7 times a day). Will his reflection cause stress or will my frequent check ins make him scared?
Ps: I'm new to bettafish.com and from now on will be referring my fish by their names. My new fish is Rufus- a male. And Katniss- female
