I woke up and he was lying upside down in the bottom his tank. He had a white patch under his chin and ventral fins.
Leading up to today he had been lethargic and not eating. He would just hang out at the surface and chill out. We had JUST gotten him so I chalked it up to stress. This is day 7 for me having him.
Our other betta in these conditions is doing just fine!!!
