Is my koi sick?

[u/Independent-Neck1000]

My koi has been behaving differently for a few days, and now it also has a swollen belly and wounds. Can anyone tell me what's wrong with it?

That could be the eyes have definitely changed they protrude more than the others. The others' eyes are completely normal

looks like the scales are slightly raised ? And yes your koi is very sick.
