Hey guys, I recently switched my betta food, but he didn't like the new food so we got the old food again. However he's bloated and getting kinda pale. I heard I can cook him a pea. Does he have to fast for a certain time first or do I just replace his food with a deshell ed pea for a day or two? Any tips would sure help. He was kinda sinking last night, but today he doesn't look as bloated, and swims better than yesterday. But he's still pretty bloated and pretty pale ( the pictures don't really capture the bloat but he's not wanting to be photogenic today.
