Are the white spots simply water stains in your first photo or actually on him?
They are just some stains I didn't clean off the outside of the bowl XD
As for him not eating, sometimes that happens if the light is out for a while and your betta falls asleep. When you turn on a bright light suddenly, they wake up and swim around but they don't respond to things. I'm not certain, but it's almost as if they're sleep swimming or their eyes have difficulty adjusting to the sudden change- sort of like when your eyes are used to the dark and then you turn on a light while looking at it. I've accidently done this to my fish a few times and tried to feed them, but they ignore it (they're fine in the morning though)
[COLOR="rgb(0, 191, 255)"]I am not sure if it was that actually XD He was swimming around a bit and noticed I was there, but was just really out of it. Same with this morning, since all of fish are up way before me lol.[/color]
The second boy with the red spot on his ventral fin looks super healthy actually, and it could just be a coloration of his fins :)
[COLOR="rgb(0, 191, 255)"]Oh alright! I was really worried about him!
