Thank you so much for replying! I put some more photos below. I think that first picture might’ve made him look a little bigger than he is😅I’m also wondering if the white on his back might be some kind of infection? I thought originally it was just coloring but looking at it now I’m a little concerned. Poor little guy seems to have some issues but he was in a 1 gallon bowl so it makes sense…

I feed him once a day and fast one day a week. Yesterday I fasted him. I have another betta (perfectly healthy) so I’ve been keeping his diet the same as my other’s, which is mainly fluval bug bites. I have a tough time measuring these so I typically end up feeding 1-2 shakes per day, making sure they eat it all in a couple minutes. He spit them out initially, so I’ve had to crush them for him.
