so i get my new ct betta the other night and i put him in a 2.5 tank next to my female betta hex and they seem to flare at each other all th etime so time to time i see my male betta go up to the filter and try to get sucked up by the filter, its kind of weird cuz its as if he was mating with a female at one point he had his body wraped around the suction part like it was a female...lol it was kind of weird maybe its natural i dunno
