Hey y'all, I've got a betta (his name is sky) that I've had for 5 months now in a 5.5-gallon tank. He's my 3rd betta in the last few years and he's been the healthiest, however for the last week and a half he's been super bloated. I've already fasted him and it didn't make any difference. I've read that I should try feeding him a pea next but I've heard mixed reviews about doing so. Any recommendations?
