Here's some new pictures. The first is from yesterday, the 2nd close up one is from today.
As you can see, that white spot has appeared in 1 day. It looks like it could be an ulcer? I'd like to know what it is so I can treat him. Every disease picture I look at online doesn't look like what I see on Merle. On the last thread, someone said it was ich, but it doesn't seem like ich to me.
I'm really worried about him, he's gotten lethargic lately.
