hey great forum.. me and my BF, having been keeping fish for about 4 years, he has 125 oscar tank, and red bellied piranha tank, we are planning a 30L communuty tank. but out of everything i think i love bettas the best.. any way my question is i have just a normal crowntail male and he tank is perfect, cover and he seems to like it. though once in a while he seems to flair up for no reason. is he justed stressed a little or is it a betta thing. my king bettas never do this. on a lighter note he sometimes goes to where he can see me and puffs up, so is he over terratorial or do i have a problem also the betta are side by side but have all side they can see each other covered. thank you
